If yours is a Tiger box, then it's probably a 25½" 28 spline box. Can you check on the tail housing ID number next time you're under the car? It would look something like "C4OR-7A040 A"
Cheers,
Glen

That is it exactly, splines, length and number.

Good guess for a shot in the dark. Thanks for checking.

Kurt, I've worked my way down David Kee's chart a number of times, and I think I need the shortest tailhousing available - the 14" version if possible. That means the C6OR-7A040-V or C7OR-7A040-A or D0ZR-7A040-A tailhousings....or a Tiger version like rsk's at an inch an a half longer would be acceptable.
Apologies for the diversion rsk, back to your thread....
Cheers,
Glen

I now have my nice new T10L correct ally-casing trans from Jim Cowles sitting next to the toploader. The tail casings are different. The reason I was having trouble getting the trans to sit correctly is that the mounting pad on the T10 sits around 3/4" lower from the output shaft centre than the toploader's mounting pad. I am using the correct-for-Cobra T'bird style chassis trans mount, as supplied by Acton, which works perfectly with the T10 but which would need a substantial spacer to mount the toploader at the correct height. Also, as a minor issue, the T10 mounting pad threaded holes are closer together, to suit the T'bird type clamping bracket.
Mystery solved - the T10 and toploader mounting pad positions are different!
This T10 is a real work of art...

Does the tailhousing length have an impact in the leaver position?
I would say now.

But what is wrong?
Do I need to move the engine angle?

ALF,

It looks like you have one of two problems going on, either your transmission is moved to far towards the left side of the vehicle or your floor pan is to wide (fabricated incorrectly). I can not tell by the photos if your transmission and mount are secured to the crossmember, if it is then your floor pan has been fabricated incorrectly. I doubt that the transmission mounting bracket is installed on the chassis incorrectly, check to see that the right side of the tail shaft housing is nearly touching the parking brake mounting bracket. It also appears that you are using the correct tail housing.
Tail housings can have different mounting positions for the shifter selector box depending on the original application. The correct tail shaft housing for either the T10 or the Top Loader in a 289 Cobra chassis is the same one that was used in a 1963/64 Galaxie both transmissions were available in the Galaxie during this timeframe, the shifter selector box mounting position and overall tail shaft length are the same. You can actually use the same shifter selector box on either transmission, the Top Loader selector box is a little more robust as the selector box pivot shaft is larger in diameter (stronger). The transmission main case is irrelevant on the Top Loader or the T10 as it can be either a wide mounting pattern or a narrow mounting pattern it does not matter as it does not affect the shifter position or transmission overall length.

Some replica manufacturers change the transmission tunnel and floor panels (as opposed to an original car) to make a little room between the seats. Most replicas use a TKO transmission with a centered shifter where as an original car would have a side mounted shifter. You can see it on an original car that the shifter is off center. That might be what's going on here.

Alf,
The shifter bracketry sits in the same place on a T10 as it does on a toploader.
What you have in the photo is very common to a lot of cars. Many of the cars I have seen, including originals, are so tightly packed at that point that modifications have been made to allow a little more clearance. Replica manufacturers tend to make the floorpan in that area work as a set of neat straight lines, which will allow the much more common T5 or Tremec or whatever to fit OK, but not the toploader/T10. The originals I have examined here have either more room or have modified floorpans to help with clearance. I actually cut and reshaped the shifter levers on my car when I had the toploader in there, which worked perfectly - and when I switched to the aluminium T10 I modified the floorpan and did some minor panel beating on the trans tunnel to accommodate it. I think your drivetrain is mounted correctly.
This problem isn't new to replicas or originals - these are all handmade cars with plenty of variation.

John, Larry and Roger
Many thanks for your help.

As a 1st steep I'll "play" with the engine mounting. Hoping to move it some mm counterclockwise.
There is some room on the safety loop. ;-)

2nd I'll work on the tunnel.
@Roger: Could you please provide some pictures of the changes you did on your car?

But the good news for me is the situation that the parts are correct. As I do this the first time I already made my mistakes.....

I would post some, but attachment file size looks to be tiny and I've given up with Photobucket! I can email as attachments if you'd like, but I need an email address.

Here are some pictures of my top loader mounted behind a 289. The clarity may not be great, but that is the best I am able to do as I was freezing my ass off in the barn in sub-zero weather. The braided line you see to the right of the linkage is the fuel line. It is tight, not a lot of room. The aluminum brace for the race seat is right up along the edge of the tunnel enclosure. You may need to loosen the motor mounts to get the proper alignment for the transmission. I had to play a little bit, moving the engine slightly more forward and side-to-side.

Good luck.

Jim

Hi Jim
Many thanks for the pictures.
Yes, I'll try to move the engine!

1795 · #55 (**permalink**) 01-05-2018, 09:49 AM

No problem. It just worked out that I have not replaced the tunnel yet from making adjustments after last years race season.

ALF,

As I had previously stated, look at the right side of your transmissions tail shaft housing, it should be almost touching the parking brake handle mounting bracket that is welded to the chassis.

Taking a look at CompClassics advice and the pictures of your floor pan and mine, I have a lot more room between the sides of the floor pan and the transmission tail housing than you do. My opening looks to be a couple of inches wider. That may be the problem. If your engine is centered and as far forward as it can go to allow for clearance with the radiator and to change belts, etc., then it may be that the tunnel opening is too narrow/floor pans too wide.
