I just got a 4l80e today the yellow tag says it was made in 98. the guy i got it from said it was in a square body 2000 chevy 3/4ton. My question is, is this swap the same as the Ls style 4l80. i know i need the 6.0 flex plate, spacer, longer bolts and the conversion adapter, but is the $150 speartech adpater the same for this trans. any help greatly appreciated.
