67 Body Mount Combination Change

I am wanting to buy and install the best kit for the body mounts and core mounts. My car was built per the assembly manual diagram like this (my combination in yellow)...




My 67 GTO had...

...Bolted mounts in positions 1, 2, 3, 6 & 7 AND free solid mounts in positions 4 & 5 (no holes in the rubber & no bolts, obviously. These are also known as "rider" or "dummy" mounts. Here's a more clear view of the positions...


My combination matches the diagram from the assembly manual (top illustration), but I would like to use bolted connections everywhere if possible AND if it makes good sense. The body areas beneath the rear seat (position #4) has the hole and the trapped nut already, even though never used. The trunk body area above the spring perch (position #5) has the hole but no trapped nut. EDIT: WRONG see below...

EDIT: Position #5 did have the caged nuts. I confused the inboard hole with the mount hole.

I have to do extensive trunk replacement work so adding the nut would be almost free. The frame has all the access holes to install the bolted rubbers.

The diagrams show different colored mounts in different locations. Can anybody help define what the actual differences are between the colored rubbers? Do the Ames Kits have any dimensional differences? I know Ames has a more expensive OEM-like kit with the colors applied, but they offer many other kits that appear to be more generic, hence me kicking this sleeping dog prior to buying. The thickness is probably the most important since having the wrong thickness in the wrong location could make the body sit poorly on the frame and bind or float. Hopefully, the thickness' are all the same and I am fretting over nothing. Here's where I hope to go...


Thanks in advance!
