hello rune
yes on the 4 bolts on all mains. i used billet fabrications
http://www.billetfab.com/pans.htm
they will make the pan to any depth. since the centerline of my crank is 6.5" from the bottom of the chassis i had them make a 6" pan. costs lots of american dollars though so be prepared. the scavenge tubes go to rt rear, rt front, and left rear. the rear bolts on the pan are accessed through the 1/2" npt threads at the back of the pan and take a little finageling, i used two allen wrenches welded together since a socket will not fit through. jeff johnston will answer the phone and make it however you want. was told two weeks but took a good month and couple phone calls.
cheers
mark
