Dear All,

that's what I have. 357 gear I think. I put synthetic gear lube castol in. do I need to use a modifier ? thanks

Yes, you still need the friction modifier.  It's for the clutches, keeps them from chattering.  I got mine from the Ford dealer, it wasn't expensive and it worked great.

yes,
you can use the trans x brand available at most local parts stores

sorry if duplicated. I have this setup , clutch pacs, do I need to use friction modifier? using synthetic gear lube. any other info helpful as I have only run w/351m, know I am doing a built 460. thanks

That's it???

that's what i did on my torino... i had 2.75's that were good, so i had my differential guy set them up on the new LSD with new bearings and seals, and new bearings on the original axles ( then i swapped housings to the lincoln mark 5 with rear discs using the lincoln axles and bearings  and housing then just placed my 3rd member section into it after the swap)

Sounda like very good advice. I may just get a new 3rd member and call it good. I always need more tools so setting up my garage with what I need first may be the right call before I dig into a project like this. Thanks again
