Dropping a 302 into a 72 mercedes

I am dropping a ford 302 into a 72 mercedes. I am having trouble finding frame mounts for the motor mounts as well as an oil pan that will work with this set up. I am planning on pushing the motor as far back into the engine bay as it will go, but the front sump oil pan that i currently have is not allowing me to go any further. Are there any oil pans that are low profile. The front sump is necessary because the steering arms are in back of k member. The other reason I want to push the engine back is for the exhaust clearance. Right now the front sump is about 10 in. in length when standing in front of the motor and i need it to be around 7 in. in length. Also this engine has the older 70's style motor mounts and I can't seem to find the frame mounts for these.

I know my ? is very general. I actually found some frame mounts from jegs that will work. there is a lot of room in the engine bay. The only problem is for header clearance because of the steering rack on the driver side. If i move the engine back about three in. there will not be any problem with the exhaust. I will prob end up either fabbing a oil pan myself or having someone else do it. Thanks for all of the help!
