[4x4k30]

update I got my ls engine set in my 79k20 my problem was the speed engineering mounts are used to install to 2wds not 4x4 the 2wd drive engine mounts are 17 and 1/4 from center to center and the 4x4 engine mounts are 16 and 1/4 . I bought a set of ls swap plates off ebay jjbb99 and they worked great they will work on 2wd and 4wd. when I first put them on and they measured 17 1/4 for the 2wd but these plates are made to just swap from one side to the other . so I swaped them around after I called the guy I bought them from and he told me just swap them around from one to the other and they measured 16 and 1/4 .
