Another 2wd to 4wd ??

[BLAZERMAN]

The 2 wheel drive frame is pretty much the same shape at the front, your 4x4 engine cradle will bolt right in, you will have to change the front core support mounts for the 4x4 versions that have the spring hangers built in. There is a bump out on each side of the frame for the E brake cables that has to be cut out and patched in with flat steel...then you will have to bore about a 2" hole in that spot for the rear upper shackle mounts along with there mounting holes. The rear spring hangers on a leaf spring 2 wheel drive frame are different than the 4x4 hangers but no reason they won't work.
If you have access to a good long bed 4x4 frame your a lot better off shortening it for what your doing.
