I posted this sometime ago but didn't get what I was looking for. Now I have more info. Car is a 1970 chevelle with a 307. I am looking for 350 engine mounts that bolt to the frame. From what i have read these mounts are different from one another although others on this site have told me different. Again, I am looking for the frame part of the mount and NOT the engine rubber mount. If anyone has a year one catalog look on page 191 and at the top left of page you will see what I'm talking about. Year One only offers the RH mount for the 350. Anyone know who makes a repo for the LH or where I can get one. Hope this solves all the confusion this time.
