Need Subframe measurement specs

[Ed Hall]

Could someone with a repair manual for a 93-94 Eldorado/Seville w/ Northstar engine look up the the measurements for checking whether or not the subframe is bent. There should be a page in the repair manual that gives these measurements. I have a 93 Allante which uses the same subframe and I suspect that it is bent. I would like to measure it before having it repaired or possibly just replacing it.

The 1997 engine subframe is likely the same. The 1997 FSM page 10-3-5 gives these dimensions (all in millimeters):

A: 1102

B: 866

C: 1152

D: 1057

X: 1546

X1: 1365

The figures show definitions of the letters as follows. They show the subframe from the bottom.

A: Distance between centers of the front mounting holes.

B: Distance between centers of the inside rear mounting holes.

C: Distance between centers of the outside rear mountiong holes.

D: Distance between centers of the front and outside rear mounting holes, measured front to back.

X: Distance between centers of front and outside rear mounting holes, measured diagonally.

X1: Distance between centers of front and inside rear mounting holes, measured diagonally.

Tolerances are 3 mm, plus or minus.

Jim,

Thanks for looking that up for me. The 1997 engine subframe has a different part # but I suspect it could be due to something as simple as different bolt holes. I'll try doing some measurements.

You have a beautiful car. A 1993 Allante with the Northstar has been my dream car for a lot of years. Good luck with it.

If someone has a 1993 or 1994 FSM they can simply look at my numbers and tell us whether or not they are the same for 1993.

Looks like Jim's specs are right on. See attached image.
