Just curious what you worked out or went with in so far as the 4l80e cross-member?

Thanks

If it is 2wd you can use the stock transmission crossmember and maybe move it. There are lots of motor mounts and adapter plates for the 2wd aplications. Pacific fabrication makes an engine crossmember for 4WD LS swaps but a minimum 4 inch lift is needed. If you want a 4wd LS swap at a stock ride height will take some custom work. I am working on that now. Lots of information in my LS swap thread in my signature.

Did he disappear(LSX72). No posts since Nov. Would be nice to see another LSX install.

Last activity was 2/03 so he might still be around?
