Description

Engine Mount Adaptor Kit Part# MM6
Install on 1969 or older Pontiac engine into post 1970 chassis
Hardware Includes:

2- Adaptor Plates
8- 7/16”-14 x ¾” Grade 5 Bolts
8- 7/16” Lock Washers

Note: It has been brought to our attention that some late 70’s Pontiac blocks have a boss that interferes with the adaptor plate. If this is the case, the boss will have to be ground for clearance or drilled or tapped to 7/16” to bolt the mount directly to the block. If drilled or tapped, this side will not require an adaptor plate. Adaptor plates must fit flat.

These may require some modification or slight shifting of frame mounts for proper alignment. Both because of thickness of requried adapter and/or "tweaks" in the frame over years of use, damage, etc
