Yes, ERA offsets the engine to the pass side about 1". Do not expect the shifter to be centered.
I hate to tell you all the trouble I had with this .. but, in the interest of full disclosure ...
I'll leave out the part where I had to make an adapter plate to reposition the hole because I changed from a toploader to a Tremec ... So I put the Tremec in neutral and set the tunnel in place and used the boot ring as a template to mark the tunnel. Used a recip saw to cut a very neat disc out. It was perfectly centered over the shifter stub ..
I was so proud!
Marked the 4 holes for the boot ring, drilled them, and mounted the boot. Test drive .. in 4th gear, when you let off the throttle, it pops out of gear
Complained to tranny vendor ... they gave me a new tranny
Installed new tranny, same problem. Fabbed new adapter plate ... moved the hole 1/2" forward ... now it pops out of 3rd gear when you let off. Jeeeezzz! Searched CC a lot on shifter boots .. the rubber accordian boot supplied by ERA acts as a spring and pops the tranny out of gear
Undid the 4 screws from the boot ring .. sure enough, no prob. Ordered leather shifter boot ... problem solved. There were also some posts about an Alpine Tiger shift boot that does work.
YMMV
