I've decided to run a couple extra pieces of this GM 90 adapter. You will save an additional $50 by pre-ordering. Once these units are in stock, the price will go up.
______________________________________________________________________________________
The GM 90° to OM60x adapter will marry any 90°-pattern GM manual or automatic to the Mercedes OM60x series. The engines this will work with includes, but is not limited to: OM601, OM602, OM603, OM604, OM05, OM606, OM612, OM647. It may also work with M103/M104, but is has not been tried yet. The crankshaft adapter replicates a pre-86 GM crankshaft with the 3.58" bolt pattern. If using a newer SBC-style transmission like the 4L60e, you'll simply need to use a flexplate from an older SBC with the larger pattern.
This kit contains an aluminum adapter plate, dust shield, high-grade 2-piece steel crankshaft adapter, hardware, and custom ARP crankshaft adapter bolts.
You supply:
-Flywheel/clutch or torque converter/flexplate
-Pilot/throwout bearing
-Transmission and bellhousing
-Mercedes Starter
