Got the Motorcraft carb pulled off the cobra and there was a 1/4" spacer plate, not metal, some type of resin. Well....so much for that idea..... Went ahead and pulled the Holley off of the Bronco and it also had a 1/4" spacer as well as an aluminum heat shield under the carb. Left the spacer on the cobra, added the heat shield, added the second spacer and installed the Holley. Started the car up and fuel was spraying out of the pressed in plug in the rear float bowl. After some research and a few calls decided I couldn't wait to order in a new bowl....hadn't driven the car in over 12 hours!!!...so I pulled the rear bowl off of the Motorcraft carb and put it on the Holley. No leak. Took the car out and........no vapor lock!!! Got my title and plates and headed home. Of course the car overheated badly and I discovered the expansion tank was leaking. Put in a couple of gallons of H2O and made it home. She's back on blocks.......
