Yep, they make different spring set ups. When converting a MII 1stGen from a disc to a coil spring the pressure plate was purple. I've never messed with one for the 2ndGen, but it may very well be blue... Or.... they got a deal on blue anodizing.. :-) Which brings up another thought. Would an early '83-'85 clutch basket assembly interchange with a newer Mark two disc type clutch basket. If it did, it would be a heck of a lot cheaper picking up a complete MI clutch basket off eBay and swap 'm out. OK they would need tweeking. New springs, discs, etc, but it would be solid....
