I have a set I brow beat out of Arrow (IIRC) as they are damned near impossible to get. Why the morons at Chrysler refuse to make this stuff easy to access I can’t say. But the road blocks are real.
I recieved word from the machinist working on my head fixture saying he may have found what he needs. If it turns out what he has won't work can I get a copy of your drawings? I agree these specs should be more available than they are. Thankyou.
