Ok I'm in the process of doing a propane conversion on a 89 22re. I need a dizzy and ignition for a cardunrated setup to complete this.
I don't mind buying new but I already have a complete 20r and need to know if the dizzy/ignition are same?

 

Why can you not use the one you have??

Unless there was a radical change in 89 you should be able to make it work.

Pull the one from the 20R and compare the physical size

Do you need to get a Vacuum advance distributor???

 

Yes I beleive cardurated dizzy has vacuum advance. I'm converting from efi to propane and was advised need dizzy from a carburated system. So I have a compete 20r that not using. I asked in pirate4x4 but was direct to ask here
