Anybody know which G-bodies (if any) came out with a 307 olds/2004r setup???? I need to know, cause i am SO close to getting my '82 Prix on the road...all that's holding me up is a crossmember...i could fab one, but i really dont want to take a turn down that road.

Eh, get a new one. They're better.
www.crossmembers.com seems to have some good ones.
83-87 Hurst Olds/442's also Regals of the same vintage. If the trans selector has the OD, it should have the 200-4r
Nearly every V6 car had the TH200 3 speed and nearly every 307 car had the 2004R overdrive.
Something like this:
Olds Cutlass / Buick Regal from 1981 to 87(Buick) or 88(Olds Cutlass Supreme Classic) were available with the 307/2004R combo.
The Pontiac and Chevy G-cars could go either way with the V8s but I have seen plenty of 305 Chevy cars with the 2004R as well.
Basically you need to junkyard search 81 and newer G-cars with V8s and then look underneath. That's how I got my last one.
Or, you can buy one from JEG's!

Is that just in G-cars? I have an 82 2004R from a delta 88 in my cutlass now. It has the B-O-P only bell housing...
My parts listings show 82 Buick Regal w/ 4.1 V6 - the 3.8 got the TH200, 82 Olds Cutlass w/ 307, 83 Pontiac Grand Prix or Monte Carlo with 305. So, I was wrong about 1981; I got confused with the body style change, sorry.

i've been trying to figure that one out myself. according to 99% of what i find(including gm) the r4 varient came out in a couple of 83 models. but somehow it was in earlier cars.
From what I have found, the first application of the TH200 4R was in Cadillacs with the 4100 aluminum V8 in 1982. I think the B bodies followed in 83 or maybe in 82 and then the G bodies got them in 1984 but around 100 or so late production 83's may have gotten it as well. According to the Hollander interchange system, they all interchange except for the Cadillac 4100 applications which seem to have used a special bolt pattern. I have also heard that G bodies first got them in 1985 and not 84, so I am not exactly sure on the year. The way to tell is to look at the frame on the driver's sied and see if it has 2 mounting bosses on the frame for the crossmember or only one. In any case, the best ones came from the performance models with the best of the best being from Turbo Regals. Newer models are better as GM steadily improved it over the years. The earliest years are best avoided as they are the weakest and GM hadn't worked out any of the bugs yet. Same goes for the TH700 R4 as the early ones have a terrible record of failures. These early versions of the OD transmissions were part of what gave GM such a bad rap during the 80's along with the diesels, variable displacement Cadillacs and the Caddy 4100 engine ( at least the early ones).
The crossmember you need will be in the rearmost mounting position on the frame on the driver's side of the car. Since your car lacks this provision (it's an 82 and was not available that year) you would also need to weld on a a new mount to the frame to properly locate a factory crossmember.

wow.
y'all are g-body encyclopedias...i appreciate all of the input...i've been to the junk yards around my area (ALOT) and sort of know my odds there.
Also, i am an avid "snooper" of alleys, fields and seemingly abandoned barns (you'd be surprised what you can find for almost no investment other than a little effort)...but i think i might be better off just modifying the 3.8L/th350 crossmember...the more i look at it, the more i see the simplicity of the mod. A little off here...a couple of welds...and there ya go....
