Hey John, Is this for the wagon? My experience would be for 66-67 only, but z-bar not the same. Pedals are same, and rod thru firewall will work, but once again 66-67 only. I've got a hardcore Pontiac buddy with 70 Ram Air IV, 4 speed car. I'll get some info from him. Wes
Here's a Buick big block Z-bar. http://cgi.ebay.com/ebaymotors/ws/e...STRK:MEBI:IT&viewitem=&item=290152624518&rd=1
