13b housing question.

[warwickben]

ok ok so for this to work turn a 13b houseing in to a 12a i would have to have to do alot of cad work ect ect. thanks.
what i got confused about was the whole coolant seal groove. couldn't think of the term before. i thought 86 and older had them in the irons so all i had to do was fly cut the housings. but i guess i had that wrong. i can do the mahcine work my self so id just need to show up at my buddys place on a weekend. if they needed cnc work he wanted just beer. but i didnt want to take a chance the came out bad.

the main reason i asked this is i got two great deals offered to me in the last few weeks. one was a set of racing beat 13b pport housing, and a new in the box TII housing. i figured if it wasnt to much work i could rebuild my 12a for less then a 13bTII swap. but i guess ill just go 13b TII swap down the road.
