Dowel pins needed??
Ok guys....Im putting in my BBC that has a front and back 1/4" mid-plate. Problem is tht the dowels that stick out of the back of the block are not long enough to stick out past the back mid-plate so that the transmission can align up and be supported. My local speed shop sold me 1 1/2" dowels. Im not sure this is long enough. Is that the stock chevy size or will the 1 1/2" work. Right now I have the ones that came with my 1978 BBC and are the stock ones. Those stock dowels are currently flush with the back of my rear mid-plate. Thanks to all in advance.

the ones I bought are 1 5/8". The midplate is 1/4" and that was part of the problem. The 1 5/8" now stick out 1/2" past my midplate. perfect. I was affraid that if I used the 2" or even 2 1/2" that I saw in Jegs/summit that it could be a problem sliding my trans back in order to remove when needed. Its a tight area right there in this tube chassis.
Thanks for the help guys!!
