Here’s my 97 cutlass supreme sl ls4 swap progress over this last year. This has not been an easy swap whatsoever, we have had far too many hurdles but we’re still goin’. First off alternator and balancer clearance was a problem, so we had to cut and plate into my strut tower about 2 inches. factory subframe wasn’t gonna cut it so we had 2 options: newer Impala subrame which around here costed a fortune, or custom subframe, which we ended building and turned out not too shabby. all custom solid motor and tranny mounts. we had to get front knee assembly from a newer Impala and axles to mount up to the 4t65 tranny, and to get rid of the horrible 1st gen strut design. for control arms we are going with stock cutlass arms and cutting and plating them to reach the Impala knuckles and bjs. still figuring out tie rods to account for track width being wider. havent dove into wiring yet but we’re almost there.

Awesome work!

You are a very brave man for doing this, all the best of luck with this conversion.

I`ll have to find a machine shop around here I like that would do that, and take them an old one to get the precise measurement. I got to looking at putting a RTSB on it and found out there isnt a single nut holding the rear strut mounts to the body. No freakin wonder the back end feels off going down the road and over bumps! I cant believe these never got a similar badge or emblem like the ACS Capri`s did, these are cool... and for the price I think I`m going to get one for the trunk lid or underneath one of the tail lights. https://www.ebay.com/itm/233771782014?var=0&mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5338590836&toolid=10044&customid=1582473de84f1b999b3022494df32e2c
