body mounting hole diameters

[boling]

What are the diameters of the holes in the subframe for the body bushings on a first generation Camaro?

I believe the two holes near the firewall and the two near the transmission cross-member are the same size. I think the front two holes for the radiator core support are smaller.

Two in the middle/two in the rear= 1.640"
radiator core support up front= .870"

Thats measured off a DSE subframe with powdercoat.

hope it helps - Rich

I am learning to use Autodesk Inventor Pro. Attached pictures show what I have modeled in 3d very roughly, so far. I have just been using data I found on this forum and what you gave me to rough out sub frame.

If I had the measurements, I would like to build a library of components. Members could ask me to check fitment digitally or just see how it looks. If a member wants to view in 3d, I can send a small version of the file with a link to download a 3d viewer called e-Drawings for free.

I got hurt in a gas can explosion a little over a year ago. Creating this library will keep the cabin fever away.

If I recall correctly, the holes on the mid and rear stock sub holes are just a little under 2"

I am currently looking at building my own subframe. I have all the hardware, GW arms, Stock spindles, so I figure why not try. I need to run wider tires up front and will only need to get the coilovers and rack and figure out what to do about my spindles maybe ATS. From what I have been able to find out, the speed tech frame is basicly a fabricated stock frame with the exception of the rack and coilovers. I would love to have an Art Morison or DSE but don't have the $$$. Do you have any measurments for suspension location and or motor mounts? I am running autocad 2000 and just started build a frame in solids. I may end up just pulling the frame off my car and build a jig but it would be nice to modle it in cad first.
