77buick 231. Changing timing chain.?

looking at front of motor , took cam button out,Then U have big gear distributor meshes with,thenfuel pump ecentric ,then the cam gear . The cam gear has 2 bolts going through it,which looks like its bolted to a round plate in back of it.Then thers the block.How do U take off the 1st gear the distributor

meshes with? Theres no bolt going through the center.

urgently needed. thanks dave77buick 231. Changing timing chain.?
If I remember correctly, the distrib drive is part of cam. If you unbolt the big timing gear, it may have a large center hole that will go over the distrib drive gear. Does the replacement gear have a large center hole?
