Motor mounts
 

what style motor mounts where used on very early smallblock Camaros

How early & what car?...Joe

1969 cars got non locking mounts in the beginning but do not now when that changed.

69 Camaro sept of 68 build

Like Salvatore said. May have had the recall cable in the early 70s or sooner...Joe

where the early mounts like the 68 mounts that used a nut & bolt through the mount or the style that just has the bolt that screw into the end of the mount

HP small blocks (Z28 & SS 350) got the impossible to find non interlocking motor mounts which are different left to right.
There were no interlocking motormounts installed on assembly line as far as I have ever seen, the running change/assembly line change occurred sometime after June - it included the bracket which installed between the block and the motor mount, a longer bolt which had a spacer and large flat washer.
These are someone else's photos - from a discussion many years ago on CRG.

I was working at a Chevrolet dealer service Dept in Boston when they had the recall to install the cable and bracket on the drivers side
