I know its not an IH, but I am working on an 84 Dodge Ram D250 318. It 'HAD' the lean burn system on it, but the PO caught the harness on fire and was a crackhead, tried to splice together all kind of different wires and screwed it all up. So now I want to retrofit GM TBI onto it. But I am looking or someone the machines the distributors(GM and Mopar) to add the GM top plate with module and reluctor to the Mopar distributor. There was a guy on Gear Gead EFI that use to do this, but I cannot get in touch with him, each number I've called in no good. Also, I 'think' I can use the lean burn distributor since I wont use vacuum advance anyway, right? Thank you for any help you can give me.
