[TECH] 3a/JH HYbrid need help...please!

[green536 at hotmail.com (Chris DeLong)]

Ok well if you have the distributor in the 3a right now and it stays in 
place then good. Next step is to remove the vacuum advance canister. next is 
to figure out a way to bolt the centrifugal advance plate stationary. And 
even after all that I couldnt guarantee that the timing would be correct. Do 
you have a 3a distributor?
