I bought a 3550 for cheap and thought I would use at least for mock-up and possibly adapt it to work behind the Pontiac(Input shaft,pilot etc)in my 63GP.I bought the BOP Quicktime Bell (PN#8070)used from a guy that had a TKO500 behind his Pontiac and is now converting to a T56.The bell wont fit over the bearing retainer.Before I purchased this trans I researched it on Tremecs website and downloaded a spec sheet that showed all physical dimensions for a TKO500 and a TR3550 to be the same except for input and outputs splines.The dimension for the bearing retainer on my 3550 is 123.19MM(4.843IN) just as the Tremec sheet says yet the Quicktime that is designed for the TKO doesnt work? I haven't yet contacted Lakewood who bought Quicktime.Did some TKO's have smaller bearing retainers?If someone is using this set-up I would be curious your retainer OD.Or if someone has thier TKO out please take the time to measure and respond.Thanks,Todd
