[67cruiser]

Ive been running my 67 gto for ruffly 2 yrs and temps are bouncing off the 200 degree mark and decided to tweek my divider plate , got everything apart no problem but i had one gasket to timing chain cover, all the stores are telling me i need 2 gaskets??? Maybe they mean the one from timing chain cover to block and water pump gasket makes 2???
But no they are saying 2 gaskets between pump and cover so 2 or 1 gasket, i have 2 divider plates in my 67,s timing cover tweeked at .030 to the vaines. can,t wait to try her out!! So 2 gaskets or one guys??????
Exactly what do i do here?? 1 gasket and motor ran fine to me.
