Are the Buick and Olds 215 manual transmission flywheels interchangeable? In other words, are the outside diameters the same? And also are the outside diameters the same whether it's automatic flex plate or manual transmission flywheel? A flywheel is the last item I'm looking for to complete my 63 Buick 215 engine with Dual path auto to a T5 conversion.......Clutch and brake pedals, bell crank, clutch linkage, bell housing, throwout fork, flywheel bolts and a T5 trans. are all waiting for the elusive flywheel ......I know I can probably get one from D&D, but their prices are a bit scary, that will be my last resort....
Thanks in advance
Should be the same.
Get a lighter one from Ted Shumacher.

I have a flywheel that I would consider selling.
