Rumor was also the X7s and other 220 blocks used spring pins in place of dowels.

This one has dowels,look at the pic full size,they're visible there.

Also the front cap was off before the pics were taken,solid dowels I assure.

Cant say they were all that way,just this one.

Lots of other details in the pics if you look close.
