Here is a Clutch Can that fits on Flash Point engines and most other engines with minor adjustments.
This clutch can has a round mating surface. There is also a clutch can with a square flange available.
I placed this behind several engine blocks I have that were made by different people and this can fit them all.
You'll need to add a small piece of sheet styrene on the front just under the oil pan.
Just the thing you need to mate that Lenco with your engine.
Resin - 1 piece.
