Building Motor mounts

I am wanting to build motor mounts for my 350 swap into my yj, but I am trying to figure out materials. should is use 3/16 plate for construction or 1/4? Also, where would I find the a rubber or polyurethane bushings?

Thanks

I'm no master fabricator but I'd use a nice thick plat and then you could go to the parts store and find the nice polyurethane bushing that fits in the space you have. sorry not more specific but each custom fab job is just that.. custom and varies on individual constraints.

The one's I purchased when I did my swap were I believe 1/4". In a case like this where you will only do it once....overbuild.

Poly will last you longer....but for engine mounts, I'm partial to rubber if you can find it. I've talked with several people who went poly bushings and were suprised with the amount of vibration transfered to the frame, and ultimately to the vehicle and passengers with poly bushings. I think they are great for steering/suspension ect...but I was happy with rubber for engine/tranny mounts. Personal preference I guess.


I like to build stuff. Want to know what I build, you can google it HERE

Thanks. Where do you think you might be able to get that bushing where the motor side if the mount bolts to the frame side?

Speedway Motor has those bushngs. They also have the mounts that are in knockdown form that you weld together.
