engine mount part numbers

[My68SS]

Hi all, just wondering what engine/vehicle these engine mount part numbers belong too.
3955183
3980938

Cheers.

edit: modified this post to reflect the correct number as per Lakeholme's post below

Looks like 67-68 302 engine mounting brackets...

Check 3955783 and see if the 7 is a 1 = 3955183...

72 P&A 30A says:

           0.029 BRACKET, engine mounting

67-68  All (302).....3955183 L.H.     2.00   engine mtg. to side member
67-68  All (302).....3980938 R.H.     2.00   engine mtg. to side member

My bad, it is 3955183. That's what happens when you hastily scrawl notes on the palm of your hand! 
Just edited the pn in the first post

So, Z28 mounts are they? Whats the difference between them and other small block mounts from those models?

Thanks for the info.
btw, the RH mount is taller than the LH one, if thats of any help or significance.

Ok, if I'm reading this right, these brackets fall into group B of the bracket list? which covers all 67 - 69 sbc excluding 69 302, 350.
Which would mean they're not exclusively 302 mounts, just standard sbc mounts covering all 67 - 68 sbc (including) 302 ?
