Where did you get that?
I made something like that years ago.
If that doesn't leak, you're doing well. That's a lot of square inches with 70 to 100 psi on it. The force will literally bend the plate away from the attachment point (the center).
The reason the factory plate works is in part the shape and mostly due to having a tall cylinder (the filter) torqued down adding resistance to the outer edge bending away from the block.
If you want to run a remote adapter, look at Canton's. Even if you don't buy theirs, those are good designs and what you should look for. Ford and Chrysler use the same filter mounting thread.
One other issue can arise with remote adapters. It should be a non-issue for a strip only car, but if those hoses get subject to really high heat from the exhaust eventually the rubber inside will turn brittle. Then hoses slowly seep oil and until you take the hoses off, and they go pop, crinkle, crackle, it the leak is difficult to find.
As far as the right angle adapters go, only once had a problem with one leaking. It was my fault. Used an abrasive pad to speed the cleaning of the gasket surface. Some trick I had just got from a local mechanic. Well that cost me three MP gaskets sets, two trips to the speed shop that had 'em, and much time on a flat plate (old bench saw top) with fine sandpaper reflattening it. Lesson learned!
