I'm cleaning up the shop and came across a box of what I think is truck motor mounts, or engine brackets. I think I have both early and later truck mounts, mostly big block but the black set is marked 360. Just thought I'd double check here before I put them up for sale. Are the straight ones the later 2wd truck mounts? I think the ones with the extra kickout bend came from an earlier truck, maybe a 1970?

The mounts in your first picture are the same mounts I had on my 76 Ramcharger 4x4. The hole in the side of the RH mount was to make room for the oil pump relief. I have those same mounts for a 440 I put in a 1979 W200. I wound guess they would be fine for any 70's 4x4.
The straight mounts I have seen for motor home 440's, but have no experience with the 2wd mounts, to know if they're the same.

First pic is 4x4 BB
Second pic is 2wd BB (I used to make them.)
Third pic is 2wd & 4wd 360 (i have a set in the shop currently)

All are 72-92 mounts
Motorhome brackets are different
71 and older brackets are different.

First pic is 75-up BB 4wd with married transfer case. 1974-up Ramcharger.
2nd pic is 72-74 BB 4-wd with divorced transfer case and 72-up 2wd.
3rd pic is 72-up 360 2wd and 4wd.

Thanks, that makes sense. I had an early 2wd big block truck and then a later 440 2wd truck so I knew they came from something I had. I think the SB brackets came on an engine I bought since I never had a SB truck.
