Not a fan of the S-10 Swap. Others will disagree. Nova, Camero, Firebird are by far the more truck compatible options. Measure 15-20 times before you cut your frame. Make sure everything is square before tacking in place. Measure 15-20 times again and do the final welds. Lots of YouTube videos on the procedure. Educate yourself and rock on!
