Good morning Paul,
To your knowledge, is there an existing BD-4 to 13B mount available?
Ben Lane
Yes we make one. It is a universal motor mount that looks like
this when applied to a BD4.
Jeff makes the beautifully NC machined adapter plate.
It is designed to use Tracy's PSRU. The rear motor mount
is built in to our 8 quart oil pan. The oil pan
has provisions for gear box oil drain back AN fittings.
