I found this From a 2008 post KTF 200r4

That trans is from a Cadillac with an Olds engine. The valvebody and govenor are not suited for turbo applications especially with bigger gears like 3.42's in our cars. The shift timing will be way off and it's difficult to modify it to make it...
I have not tried my 15" wheels with the conversion, I'm running 17" wheels.
They list this conversion compatible with 15" wheels but I have heard that .
some rims with poor welds did rub. (Steel Wheel)
Maybe others will chime it.
I'm in Connecticut I had my new OEM ones painted maybe 12 years ago.
They were painted inside also still great condition.
the painter is in RI and painted my car in 2002
I could check on a price to redo yours if you like.
