I got a 98 Bravada that won't engage front wheels, not sure why but it blows the fuse every time it would try. I was thinking that I would like to do a Blazer 4WD swap, and possibly even an auto>manual swap as there is a low mileage manual blazer with a cracked block in my area that I could siphon parts from for cheap. Is this a 1-1 swap or would I need a ton of fab to get it going?

Also, any ideas on the problem with the AWD blowing a fuse?
