I'm in the middle of a 5spd swap and I went with Fidanza for my fly wheel. Today I got it attached to the crank and it looks like there will be very little, if any clearance between it and the bell housing. I haven't jacked the transmission up to check it further yet but it looks sketchy.
Here's what it looks like towards the back of the block.
The flywheel's part number is 191221, I'm fairly certain it's the correct one for a prelude. Those of you who have or have had a Fidanza flywheel, do you also have very little clearance towards the back?
