I have the largest diameter bearing support bellhousing,



There are 2 different size front bearings and 3 different size bearing retainers. Brewers can get you the correct one for your case or an adapter ring to make it work.

not sure what type yoke I have...any additional strength benefit in the cast iron side cover and tail housing?



The weak link tends to be the countershaft bores in the aluminum case. I have never really heard of problems in the side covers or tailhousings. The countershaft wallows out the holes and lets the gears walk around a bit. Not good.

The other weak link is the interlock levers tend to break but this will happen if it is iron or aluminum side covers. Hence the reason I like the ball & Detent side covers.

So it looks lime I should be able to swap the guts of my aluminum OD case directly over to the cast iron case with problem...and brewers can tell me if the kit I need will be any different...sound about right?





Yep.
