Cutlass tranny cross member

[2fit661ca]

does the cutlass use a smaller crossmembers for the transmission than the other g-bodies??

[Blake442]

Nope, same as every other G-body.

i am asking this completely from memory, but got to get a good look under my 86 yesterday for the first time, and if i remember right, the cross member for the tranny is only about a foot wide and bolts to the chassis... is that right?

Memory is the second thing to go, and you probably can't remember the first...

No, that is not right. The crossmember runs from frame rail to frame rail. Ignore the vendors who claim their crossmembers won't fit Cutlass Supremes, as they are idiots who won't respond to attempted corrections.

yeah O.E.M. there are just 2 G-body crossmembers .... for the th200/th350 and the 200-4r. IDK where the whole Cutlass Supreme thing came from but I've seen it on crossmember and header subnotes. To the best of my knowledge the only "offset" engines were the Turbo Buicks and they just used a different transmission mount to offset (aprox 1" forward and 1" to the driver's side) - they still used the same crossmemeber as say a 442.

i don't care in the slightest. i just need it fast and i need it cheap. i don't have room to be pickey as long as it will fit my cutlass application and won't break in a years time.

[cdg1984]

I got one off jegs for about 100 bux ( i think ) if u consider that cheap.

That "foot wide" piece you speak of is just behind the trans x-member.
It's a fail-safe for the driveshaft so it doesn't hit the road if it lets go up front.
It bolts to the floor pan. Pretty much every "bolt-in" driveshaft loop for a G-body bolts in there.

Actually, I'm pretty sure it's a body stiffener. I doubt GM ever cared about a factory driveshaft safety loop.

[2fit661ca]

what ever it is, i could do both tasks, and it is not needed to drive the car, so...

Minion offered me his crossmember, so i should be good to go. now i just neeed to find a drive shaft

[Minion1186]

yes i did,its in very good used condition,thank god someone needs it,it would be in the trash right now if not.

Too bad you are all the way in Iowa..... I've got one that you could have that already has the cutout for the dual exhaust.

Check out this other one I found too. Read somewhere that the Iceman Fab crossmembers were heavy.... Not sure how that could be but this one says it weighs under 5 lbs.

Iceman used to produce one that was pretty much identical to the G-force crossmembers. However had to change the design when G-force sued or threatened to sue him.

I have on of Iceman's original T-56 crossmembers before he changed the design:
