I'm having to replace my cracked 251 in my 66 FFPW with an NP420. I have a 242 from a 1941 Chrysler that had an automatic. The 242 has an 8-bolt crank that has a hole bored in it that I think is 7/8", my caliper won't quite reach in far enough for a really accurate measurement. I haven't pulled my 251 out yet. Is the 251 the same, and if not, is there a pilot bushing that will let the 242 accept the NP420? Pics of the 242's crank are here
