This is as close to NOS as you are going to find for a vintage adapter. This has been my wall hanger for many a year and I’m cutting it loose so someone can put it into service like it was meant to be. This is a 2 part adapter. Both parts are here. The engine side is marked 0400. The transmission side is marked 0401. There is a bag attached with the no-see-em can’t-find-em pilot bearing. There is also a paper which I assume are instructions, a water slide decal and some bolts and washers. From the Offenhauser catalog. For 32-48 or 39-50 Mercury & truck transmissions thru 52. Chrysler Plymouth DeSoto Dodge all with ignition mouted in rear. I reserve the right to be wrong. All information here has been taken from the 1981 Offenhause catalog.. This is the go-to adapter guys are looking for to put a’39 Ford 3-speed box behind a 50’s Mopar Hemi. 1952 1953 1954 1955 1956 1957 1958 1959 1960 1961 331 354 392 276 291 330 345 241 270 315 325 260.
