I was thinking about something.. I'm eventually going to try and have a 4T65-HD diff and diff cover in/on my trans. I know that the 4T65-HD housing is longer than the stock 4T60/65. It'* nice that the GP guys don't have to worry about this but my rear transmission dogbone mount bolts to the end of the cover. So if I'm thinking about this right, there should be a different part number between my and a 96+ ssei rear dogbone mount.
Could someone look up the part numbers for both mounts?
And does anyone have a pic of the 96+ ssei mount?

Dude, it mounts to the other end, I don't think you'll need a different mount.

Are you sure??? *Goes out to crawl under car in the street at 10:30pm*
Edit - Crap it'* raining.

Heres a pic of the mount I'm talking about:

Don't those two bolts holes bolt up to the diff cover?

yeah, where the diff cover bolts to the tranny.

Somebody compare them in the magic book. I don't have mine handy. Otherwise, I'll hit this in the AM if you PM me.

22112485 for '95 L36 + ALL 96-99

All 96-99 includes L67 with the HD?

Yup. That'* what it says...

Confirmed....now that I have the book right here. The only difference was that the 92-95 SC used a different dogbone strut than the 92-94 L27. All Series 2 L67 and Series 2 L36 use the same one.

This is because the HD trans from 92-95 used a different case and output housing. Not true with S2 apparently. (Series 1 L67'* used the same beefed-up case the 4.9 liter Caddy'* used)
