12A to 13B conversion

in order to convert my 12A to a 13B, to put the main block together, do i need anything besides rotors, eshaft, and SE housings?

for the main block i would need the dowel pins and tension bolts, for the rest of the engine i need the front and rear counterweights, the rest of the front parts are the same so i dont need different ones right?

so the list is...

SE Rotor Housings
13B Rotors
13B Eshaft
4 13B Dowel Pins
13B Tension Bolts
Front & Rear Counterweights to match whatever rotors i use

is there anything else i need? there are 4 different types of tension bolts for 13Bs, i know i need 17 since the 12A rear side housing is being used, but how many of each kind do i need? for 12A there are only long and short, for the 13B there is long, long ribbed, short , and short ribbed. thanks in advance

edit: ok i found out the ribbed ones are for 89 and on engines so i just need the other ones, but damn they are expensive - 15 bucks a piece! thats gonna be over 200 dollars if i buy new ones!! i will definatly get a used set.
