I rebulit my powerglide that i'm bolting up to my 250. I got a new torque converter with 10 1/2" bolt spacing. My original flex plate and converter is 9 1/2" bolt pattern. Does anyone know of a new flexplate that will work? One manufacturer told me that they had a 10.5" flex plate that would work on 250's up to 350's but that the 250 crank diameter is different so it "may not" fit. Any ideas on a new flex plate.
