A Tremec TKO-600 has the same bolt pattern as a wide case toploader so your all set there. The issue is with the length of the input shaft. The TKO-600's ia 3/4" longer than the toploader. In order to install the Tremec tranny behind an FE you will need a spacer. McCleod makes one for a cost of approx. $150.00. The other option is to remove the input shaft, shorten it and reinstall it. Forte's parts connection does the input shaft shortening modificaiton if you want to go that route. Keeep in mind that in you use the spacer, your drive shaft will need to be shorted. Hope that helps, have a good one.
