Crossmember Fab ?

Making a removable engine crossmember for my 83 dodge w150. When I did the ton swap the high steer ended up to close to the existing one.

I going to maintain the upper portions where the engine mounts currently sit. All I'm doing is replacing the portion spanning from the bottom of the engine mounts under the oil pan.

Question? How far from the bottom of the pan should I go? I'd like it to be about 1/2" but don't know if that is to close. I don't see there being that much movement in the rubber mounts.

This was in newbie and I know I missed Tuesday.

I don't expect the 30 year old mounts to compress much.
I just never saw how much they would allow movement during shift/throttle applications.
I can't imagine my little 318 twisting em that much.

You just reminded me that my oil pan is rubbing too
It was about 1/4" with new Energy suspension poly mounts. Now it touches, but it ain't leakin' yet!

I think 1/2" should be safe and also clear your steering.

Your also fighting against the frame flexing as well..Get the truck twisted up and it may touch.


The dodge mounts tear easy..So account for that..I had a tired out 318 in my last rig and i replaced the mounts a few times..

Thanks angryblack,
I'm concerned about the rubber after seeing "jopickens" post his mounts. Definitely on my to-do list to replace them.
Just need to get her dialed as far as rough ins go.
Got the time off till new years and hope to get a lot of loose ends buttoned up.
1/2" to 3/4" is as far as I hope to go.
