    Default Rear axle swap

    I have a 1983 olds 98 regency brougham. And my 13x7 reverse wires don't tuck behind the skirts. Will a rear axle from a malibu or elcamino be shorter to allow my rims to tuck

    Any G Body rear would work.

    You need to measure the over-all length of the rear. Then compare to other G body cars. I believe the track width is the same on all G bodies. A s10 4x4 rear might work, however you will need to get the brackets welded on to use your stock trailing arms.

    I think a g body width is 58" but its not gonna be bolt in, in most cases u need to cut the brackets off both rear ends and reweld the old ones on the new rear ebd plus u need the pinion angle correct

    So basically just swap the brackets from one to the other?

    Yeah, you can use the brackets off of the original to use on the new rear. Try a 70-81 fbody rear or S10. Sit it in place and find your pinion angle. Then weld your g body brackets on.

    Looks like a s10 rear will work for you.

    this is how I wuld do it take sum measurements before removing the old rear end. also while the car is up in the air u can get the pinion angle off the old rear end.

    Yes, but make sure to use adjustable upper G Body arms.

    The 2006 Lincoln Towncar rear end will work but I think it requires a full chassis swap

    If you do not want to Go threw all the crap to modify a new rear end to fit in the G body the correct way you could always remove your stock rear end and take it to a shop to have them cut the rear down. It would be the same as narrowing a rear end for a hot rod for drag car. That way you don't have to worry about the suspension geometry and pinion angle. It will be a bold up application. It will just cost a little bit more. I believe speedway sells shortened axles for the G body.
