Lightweight Flywheel size 215 vs 225mm
My engine is a 1979, and has the 30 pound boat anchor of a flywheel on it. I'm planning to replace it with an aftermarket lightweight steel unit. The transmission appears to be a 1981.
I was wondering if there is any reason to stay with the 215mm flywheel over changing to the more common 225mm? It seems that parts for the 215mm are starting to dry up.
Also, as I understand it, the only parts needed to convert are: flywheel, counterweight, pressure plate, and clutch. Am I missing anything, or is it just that simple?

Don'f forget the pilot bearing too.
You can also get a stock 82 flywheel that will only be 23 lbs and it works fine on the SA 12As with no changes in balance required. I have this on my car and it makes a world of difference and its easier and sometimes cheaper than the lught flywheel options out there.

The clutch only has to match the flywheel. Use whatever clutch you need to.
You can also use a 215mm disk with a 225mm clutch for marginally better shifting. I had to do this for a friend's car when every clutch set he ordered for an '83 engine was miscataloged and he kept getting 215mm sets. So we put a good used 225 pressure plate on with one of the new disks. Worked just fine.
DON'T REPLACE THE PILOT BEARING unless you have reason to believe the old one is bad or the O-ring is missing. Pop a little smear of grease in there and keep on truckin'. You are more likely to damage a new one on installation than you are likely to have a good used bearing fail.
