I apologize if this has been asked before, however I was looking at rock auto for new motor mounts since the rubber on the ones in my truck are deteriorating. They have 3 different options, early design, 2nd design, and late design? ( truck is a 1979 f150 4.9 manual )
The mounts themselves should be the same for a 300/4.9 (I would think), but the brackets off the frame for 2wd vs 4x4 are very different.
If I remember correctly the left/right are different on 300s, but you could always check LMC as they have decent pics on their site, most of the time.
If you get desperate and nobody else that has one responds, let me know and I’ll go digging in my shop. Ive got a few 300s laying around that i can check.
