i got a 93 f150 4.9l and the engine mounts on their now are those round ones and i had gotten the frame brackets off a 95 or 96 f150 for the older rectangular style mounts and i am wondering what side the brackets go on? i got a skinny one and a big one. its been about 2 months since i took them off the truck in the junk yard and i cant remember what side they go on.
