Suede, was this thing also made 2WD only at the time of the swap? The THM350 is a good swap and the converter is smaller then a V-8 unit for a touch higher stall. A 10" will do the job for 292's and a lot of 250's. A lot of earlier converters were 9" and weren't much of an overheating problem because of the smaller cubes. If it is still a 4WD, the tranny is an easy coversion using the right transfer case. If it still 4WD, do you have the old Borg Warner or Dana Transfer case installed still? If it has gone to 2WD, put the unit in and have a driveshaft built for it. You'll enjoy some boppin' around town with it. By the way, no adapter plate required, just keep the starter and flex plate matched. No big deal at all.
