94 Lt1. Driver's side pretty easy, pass is alittle more involve. Looks like two ways to get to it. One way from the top by removing the alt. The other way from the bottom by removing the starter and possibly the exh pipe. Jus wondering how you guys did it? Thanks

 

well with my headers its easy. stock exhaust,,, notsomuch. i went at it from under, removed starter and pushed it forward. get a socket that fits tight. i had to beat one (socket) on, well tap it on as hard as i could and if memory serves, used vise grips to fianally get it cause rachet wouldnt fit. little bigger socket was trying to strip it.
my sensor was a twisted piece of scrap when i got done.
