Thread revival..... I'm set on using my R150F transmission. I talked to Glenn at CRS and he told me that their bellhousing should work as long as my truck has a 160mm input shaft. I've only found one source online that could verify that input shaft length. I'm going to call Marlin Crawler tomorrow and find out. Has anyone on here used that specific bellhousing? If so, did your stock clutch fork work? Thanks, Eric.
