I am not following the od part of that swap, those fullers come both way in od and in direct, seems to me he has made a direct into a od by swaping out some parts with another fuller that he just subsituted the needed od gears and shaft, a real truck tranny shop can do this all day long, trick is to find one!!!!lol I WISH i was next door to one for sure, then i just try to get a fuller in sae 2 to bolt on the front of my old spicer aka now dana aka now fuller 3053a spicer sae 3 for the m35. I am still waiting on the 5 ton clutch housing off of a M54 5 ton army i bought to see if it bolts on the spicer 3053a to avoid the $600 adapter for my next swap, this one is about over, all i need to finish a the Freightliner FL60 parts book i ordered from San Antonio Texas Freightleiner Rush Dealer to arrive so I can order the front engine mount for the 5.9 used in the freightliner and the master clutch resovior for the firewall, the hoses, the master clutch slave cyliner and mounting bracket, all of which will be avaialble from Freightliner anyehre in the usa with my parts numbers i willl be posting up soon as well as the phone numbers and parts numbers of the made in china Cummins replacments for the SAE2 @ flywheel housing $300, sold in San Antonio Brake and clutch and the matching 5.9 cummins replacemnt SAE #2 flywheel made in China, $250 new, the clutch disc will be made to fit the 1 1/2 dia the 3053a spicer has and will be in 14 inch dia for. So what does this all mean, anybody now who wants to use a 3.9 or 5.9 can simply order the parts from an aftermaket truck parts house and also the Freightlliner dealer itself and only need a custon clutch disc made up and i still need to figure out what cranksaft bearing is needed frot he spicer 3053a insput shaft when installed in the cummins 3.9 or 5.9. When i take my old sae #3 spicer 3053a 13 inch clutch set up to San antiono brake to supply the new required 14 inch clutch for the sae #2 Freightliner FL60 set up i will have matched up, all then needed is to get all stuff ordered in from Freighliner for a 98 Fl60 with a 5.9 cummins with 5 speed fuller with 14 inch clutch set up hydralicly. Getting close for sure
