Bell-housing alignment help

I think I'd look at two solutions. Give ROBB a call - see if they can make you a set of .027 ofsets. Or get some shim stock and egg the holes in the bell so you can place the shim stock under on side of the pin, offsetting the bell the rest of the way. Also make sure the bell bolts are not holding you back not. SOmetimes having to move it too far means the attachement holes might be so misaligned the bolts hold the bell off position.

I already had to egg the bell bolt holes to get it to even accept the 0.021 dowels.

Robb said CNC'ing a 1-off part would be absurdly expensive. More than $100. He suggested drilling out the alignment pin holes, bolting it on, beating on it with a mallet until it was aligned, drilling out some washers to be snug-fit over the pins, slipping the washers over the pins and welding them to the bell, to keep it from moving.
