    possibly a spacer, modify the crossmember, modify the harness, get someone to upload a file for the 4l80, stall.

    that answer was for you too Alton.
    I dont expect any big deal as far as your crossmember goes. There are several locations to move it to and should be easy to modify.
    The spacer runs about &#036;30.00 and the longer bolts neede run about &#036;30.00 from G.M. part #&#39;s 12563532 & 12563533
    I would think Allen could take care of the program w/o a problem.
    THe harness,if Allen doesnt have it is &#036;160.00 from Speartech.
    THen, the more expensive stall.
