Welcome! There's not a lot of V1 owners here uunfortunately, so you may not get much help on this particular subject. All are welcome, but it's mostly V2 & V3 owners. Plenty of LS engine knowledge though. You might get more responses on LS1tech. At least when I had my '05 they had a pretty active V1 forum, but that's been a few years ago. Or maybe a V1 FB group? Good luck! I had the FG2 suspension and even several years ago they were impossible to find.
