The spider washers will NOT slip in after the gears are in position. The washer (spacer) is stuck to the back of the spider and then both are rolled into position at the same time. You can remove the spring pack IF you can compress the springs till two halves are tight against each other and fasten them there. I used a dot of brass to hold till back in place and then just heated one dot. When one dot melted WHAM the other broke and the spring pack was in place. I don't think a 12 bolt was offered in 1976 but was in 66-67 with the 350hp 327 and in the late 60's big blocks.
