Some times you can use what you have and just evenly cut the spacers to get everything to line up, although it's harder than it sounds. Other times you can pirate stuff off another engine that will work, say the same engine in a different model setup? I know a few places will even manufacture pully and bracket setups for you out of billet, but that gets real pricey. You also can try looking on ebay for that engine series parts and see if any of the brackets would look like they would work for you. This is a tough part of mixing engines and bodies from different stuff that we all run into. The best solution usually is finding someone else using the same engine setup you are, and seeing what they came up with. You'd be amazed what you can stumble across on a carefully worded goggle search. You might even go the a forum that specializes in your EFI engine and ask a few questions there, I did that on Ford Truck Enthusiasts ith my 460/ 1948 Ford truck and found about 20 people with the same setup, that were very helpful. I hope this helps, Steve.
