To get everything to line up properly with an FE, ERA prefers to use the spacer between the Tremec transmission and the bell housing. Remember, if you move the transmission 3/4's of an inch forward with the short shaft, it's going to put everything attaching to, and behind the transmission, that far off as well. I have the spacer on mine, and it's something you really never even think about.


The Big Danger -- if you use the longer input shaft, and you don't use the spacer, and you just jam it all together and tighten it down in blissful ignorance, then the input shaft will bottom out on your crankshaft, push it forward, and you will toast your thrust bearing in short order. That will be a sad day for your FE.
