I put together a 65 Dodge Dart rag top about six years ago.
It had an automatic. You could push start it, or tow it in neutral. They had a front and rear pump in the trans.
The rear pump is what made it possible. I sure do miss that car.

Well on my way to becoming that eccentric old man in every town.(crazy as a s#@thouse rat) With a yard full of desireable old vehicles that tells you, Sorry they're not for sale..... Someday I'm going to fix them.
