66 poly 318 trans behind 340 in 71 Demon.

there were numerious brackets used on the trannys over the years between the 904 and 727. i used a bracket from a /6 904 from a 70 duster to finish my 318/904 in a 69 vailiant. and yes, the cross shaft should be level. where was the weight on the convertor? a 69 340 should be neutral balanced.
