Willys Jeep 4 Speed Swap: Adapters!

In this video I walk through all the steps it takes to adapt a Ford t18 transmission to a Dana 18 transfer case and a Willy’s F head (Hurricane Engine) or L head (Go Devil Engine). The input shaft used comes from a Jeep J truck with a t18 and is machined down to match a t90 input shaft. The front bearing retainer is completely custom. The transfer case adapter comes from later cj5 Jeeps and full sized Jeeps with the t18 Dana 20 combination. The bellhousing is a stock F head bellhousing. Machine work was done by a local shop and by mosier engineering. Should apply to cj2a, cj3a, CJ3B, and cj5. This is an exciting part because after the adapters go on I can start dropping gears in and building the cases!
