Just bought a newer (mid 60's)235 to replace my old ('51) 216. Haven't taken the 216 out yet because I'm not sure if it's gonna work. I've been told it will bolt right in but the bell housing is different. The 216 has the 6V starter go through the engine housing (above oilpan) where the 235 has the 12V starter below the oilpan. Any thoughts on possible problems?

Thought I'd ask before I get home from work and actually take the 216 out.
