One more question, since the 4.3 mount worked on the pass. side, and the 5.3 mount on the driver side, would I be able to do a switcharoo and use the 4.3 mount on th edriver side and a 5.3 mount on the pass. side?

 

Use the 5.3 on BOTH sides otherwise the motor is off center and the whole engine will be moved

 

its so wierd. the 5.3 frame mounts I have now, well the passanger side fits on there perfectly, but the driver side mount doesnt. The two holes the big bolts go through on the actual mount, well they are to close together, so the bolt holes wont line up on the frame.
