Hey JM,
 This is great information! Can you tell me where I could find more info like this? I've got one of the early 90's T-Bird IRS set ups in the garage. (or, as the wife calls it, 'the bermuda triangle'. projects disappear into it and are never seen again...) It would be helpful if I could find dimensions for the rear subframe mount points in the T-Bird.

 Grin Cheesy That's funny! Cheesy Grin

Dave, I found those spec pages a few years back while searching for information on reinforcing the G-Body frame. I don't recall seeing any info on other makes & models. I will try to look back into my Bookmarks, memory, etc, and see if I can't find something more for you. I have a feeling though, that I probably won't be able to locate anything more.


EDIT: Additional info. Dave, I looked through my stuff & all that I could come up with, was the name of the publishing company. 1983 KLM AUTOMOTIVE PUBLISHING INC. You might try searching with variations of that & see what you find. Good luck & please let us know if you find anything else.

Metric Frame Info
I ran across this last week and I figured there would be a few others that would like to save it.....

1978-1988 A & G-Body Chassis Information

The purpose of this page is to try and document some of the FAQs about the '78-'88 A& G body cars. The majority of the cars produced were the Buick Regal, Chevy Monte Carlo, Oldsmobile Cutlass, and Pontiac Grand Prix. The earlier cars include the Chevy Malibu ('78-'83) and El Camino ('78-'87), Pontiac Bonneville ('78-'87 4-door), and Pontiac Grand Am and Le Mans ('78-'80 2-door). GMC also had their own version of the El Camino known as the Caballero.

- Body Mount Bolt Information (1982-88)

There are three different size bolts.
Position 1 uses GM P/N 10049638 (sold ea., 2 needed). Bolt is 12 X 1.75 X 95mm long.
95mm is not common so you have to use 100mm.

Position 3 uses GM P/N 14085301 (sold by pkgs. of 5, 2 needed). Bolt is 10 X 1.5 X 55mm long. Also need two nuts.

Position 2, 4, 6, 7 uses GM P/N 3524497 (sold by pkgs. of 5, 8 needed). Bolts are 10 X 1.5 X 80mm long.

- Interchangeable Parts Between the G-bodies - Mechanical

Complete front suspensions (Upper/lower front A-arms, spindles, calipers, steering linkage, steering boxes)
All Brake Parts (lines, hoses, calipers, pads, rotors, bearings, etc.)
Dual-diaphragm brake boosters can (and should) be swapped for the single-diaphragm boosters
Complete Rearends (ex. an '87 Monte SS posi 3.73 rear will fit in an '81 Olds Cutlass)
F41 Sway Bars into non-F41-equipped cars
Grand Prix triangulating frame brace (ties the lower F-41 engine cradle-to-frame bars together)
'78-'80 4-door Bonneville fender braces or '81-'87 Grand Prix fender braces (from fenders to upper radiator support)
Entire Engine-bay HVAC assembly (where A/C and heater core mount to firewall)

- Interchangeable Parts Between the G-bodies - Interior/Exterior

'81-'88 Olds Cutlass coupe doors fit '81-'87 Buick Regals, and vice-versa
'81-'88 G-body interior wiring to add or repair power windows/ locks/ trunk
Steering columns between similar years
All weatherstripping (coupes)
Outer windshield trim and wiper arms (coupes)
Drip-rails above the windows (coupes)
Lower door panels, along with most upper door panels
Most interior trim (A and B-pillars, factory T-top trim, lighted vanity mirrors, and headliner boards)
Seat belts and actuators
Stainless-steel "Body by Fisher" door sills
Front seats (bench or buckets. To install buckets in a solid-bench car, get the bucket seats, tracks, and mounting plates with studs from the floor of the donor vehicle, and weld the plates in.)
Rear seats
Rear package shelf (and CHMSL for '86-up vehicles, fed. mandated)

- Additional Parts from Donor Vehicles

'82-'02 S-10 upper/lower A-arms and spindles
'82-'92 F-body lower front A-arms - steering stops need to be ground down, but fit perfectly
'82-'92 F-body lower rear control arms
'82-'92 F-body front sway bar (34 or 36mm bars)
'82-'84 F-body aluminum rear brake drums
'87-'92 F-body aluminum radiator (5.7/auto application - Modine 951)
'87-'92 F-body XH steering box for 16" wheel upgrade
'88-'92 F-body serpentine belt setup for SBCs - use F-body alternator, p/s pump, A/C compressor, condensor, and lines
'78-'96 B & D-body front spindles for 12" brake conversion
Note: The big-brake upgrade with factory parts requires aftermarket tubular upper control arms. '78-'90 is trial-and-error; most cars got 11" brakes, while wagons and 9C1s recieved the 12" brakes. A sure-fire winner for 12" brake spindles is any B-body from '91-'95. 1996 B-body taxi/police cars and & D-body limos have larger lower ball joints, so these spindles should be avoided. Regular '96 B-body spindles are fine.
'84 S-10 manual brake drum rear wheel cylinders (Raybestos WC37644)
1990 B-body master cylinder (Wagner 104660)- for use with 12" brake conversion
