I am trying to get my 4 speed mounted to the AA SBC kit, had to order new dowel pins part 90250-10192 as they were missing in the 4 speed that I sourced, and the holes in the trans for the dowels are WAY bigger than the dowels. No way they work, they fall through the bell housing and into the clutch assembly. Under the gun here, as this weekend is scheduled to be the drivetrain swap. Thanks in advance!
