Just got ahold of a 40 convertible

w/ a 51 merc EAB head engine with 5/8" belts and 4 blade fan. Thus not real sure of what the engine is. Has the left rear oil filter canister. My main question today is transmission oriented. Will the trans and rear end be changed due to the later model engine being utilized? I read where the bellhousing is no longer attached on the 49-53 flatheads. I am needing to order some transmission parts. New 2nd syncro and other misc. Some input would be nice.

The original transmission can be used with that engine using the 1/2 bellhousing used with Mercs and trucks.

The original transmission and rear can be retained if a '48-'52 truck/'49-'50 Merc 1/2 bell was used to mate the late engine to early round pattern transmissions. A picture or two of the engine/trans taken under the car will show any changes that were done.
