I can do that, too. No problems with the '78 distributors when properly refurbished. I have all the parts needed for the refurbishment, except I only have single diaphragm advancers without the High Altitude Compensation. OK if yours works, but given your location HAC's probably not needed anyway.
PM SentI'm refurbishing FJ60 distributors, including new NipponDenso advancers. I adjust the advancers to match the advance curves of specific F and 2F engines, and have done quite a few for '77 through '80 2Fs. I think @ToyotaMatt has a coil/igniter. I use OEM parts in my refurbishments (cap, rotor, O-rings, etc.).
PM me if interested.
I'll look at my remaining parts and see if I can put a package together for you. I know I have an advancer, cap, dust proof packing (for the cap), rotor, O-ring, mechanical advance weights (with sleeves), stop pin bushing, and ball bearings for the breaker plate. I'll have to see if I have an extra set of races for the breaker plate in case yours are pitted by the ball bearings, which is pretty common. Pitting causes the breaker plate to hang up as the advancer tries to rotate it. I've been able to sand the pitted areas of a marginal race, but not if the pitting's really bad.If I wanted to clean up and run the 1978 can you sell me the parts?
Are those the same as a celiac?
