I've looked in my factory service manual, haynes manual & search the internet, I even called the dealer. I can't find the specs I need.

Short of getting the tape measure out I thought the veterans of the forum might know the exact specs for a 1991 or point me in the right direction.

Wheelbase, width & curb weight, if you know engine & tranny weights as well if would be a big help.
Thx

Nice job, Pat. Can you get the wheelbase for a 90? I'm just curious cause of the 97 fuel lines in Franky. They fit well but seemed to be about 3/4" long.

If memory serves correct, GM didn't completely revamp the H-body chassis for 1992, so it retained the same 110.8" wheelbase

Thx BillBoost37

Perfect! now I know I can use the suspension from a STS (111") .200 thou is close enough.
I didn't want to use the 113.7" I have from the Concours, it would throw off the tight cornering.
