Found the below on ebay
BMW Getrag M60 Dogleg Box - M20 Engine - 325, 323, 320 - E30, E21 etc | eBay
Do you reckon this would line up to a M50 engine? Its from an M20 so i know the bolt pattern is the same, just wondering about the rest?
The 325i race car already has a m20 flywheel and e21 323 release bearing, so this should match i think
Lastly, is this expensive for what it is? 6 years ago my and my dad sold one for nearly nothing
