did you notch the crossmember? coz an un modded sump would mean the engine is sitting really high
also can use L20b ruber mounts as they are smaller than R30 ones, meaning engine sits lower

mine with an L20b could still fit the stock carby and filter assembly with a 10mm spacer under the carby

and auto tailshaft only works with 1200 and 120y BW diffs, h145s and h150s as there was never any auto utes...so for a ute diff you need to cut down something else, stanza or bluebird tailshafts have the right ends
