I have what i believe are the orig. motor mounts to my COPO. Does anyone know the part number to these mounts? Thanks in advance,
Mayor of Fishkill

I have a L-78,69 SS, and I purchased a set
of N.O.S. pieces for our car a while back.
On the Part sticker on each Moter/frame mount are the #'s 3980941 and 3980942, respectively. I think the last four digits
of the number are stamped into the frame mounts also, on the lip that the bolts go through to the frame. Now I am not sure as to the fact that these are service replacements, or the actual assembly line parts. Joel

of the number are stamped into the frame mounts also, on the lip that the bolts go through to the frame, facing upwards. I haven't looked at the parts in a while, and they are buried in the garage. Now I am not sure as to the fact that these are service replacements, or the actual assembly line parts. Joel

I believe the motor mounts in my car are original. Is the part # visible installed?

I haven't been in the garage yet. But I think I am correct in the assumption that the COPO L-72 and RPO L-78 incorporate the same frame mounts. I will look this Monday as I am off and will start spring maintenance
on the L-78 and I will check for you.....Joel

OH, those are the engine to frame mounts.
I still have to take a look, and I am not sure of a # on those........Joel

3937930 is the correct # on my 396

My origianl motor mounts on my 69 Yenko have the same number for the RH and LH, which I see no difference. Embossed in the rubber is
3937930 BLUE and a number below 3920627 AU 10 for both left and right.
