i recently did a frame out restore on my 87 it was changed over to a 89 motor for it's a much better design. any how when installing the piston there is a spacer on either side of the rist pin bearing. my ? is can i remove these without causing problems. i blew my motor when this washer let go and i don't want it to happen again. if any one has an answer it would be great because noone else does.
