4 Speed Conversions Retailer

4 Speed Conversions - GM Manual Conversion Parts Store

This retailer/website have been super valuable for me as a novice GM builder with regard to transmission and clutch stuff (Novak got me started, this got me the GM specific details of part numbers etc)....Although there is a lot of universality to GM stuff from the 60s-70s, there are still some important differences and this site has both information and parts. More geared towards the restoration and muscle car crowd, but still really helpful for me with making sure I knew what to look for with regard to the larger 5" 'truck' bellhousing front bearing retainer and the correct dust shield and various other stuff. A lot of aftermarket parts for the classic '621' aluminum bellhousing, but harder to get info and parts for the 486 or 576 ones. Also, has lots of info and parts for the early cast iron, open bottom bells. Anyway, just thought I'd post it...can be deleted if its too far removed from jeeps.
