Yes, dont use the perma cool universal type. The cheapo aluminum ones do not seal to the engine well and have been known to leak.
Now you can use the perma cool filter mount, lines, clamps, etc, but when it comes to the part that attaches to the block, skip any of the cheapo pock metal looking units.
I did alot of research on this before I did it for my conversion, I found a company called Canton makes a billet 360 degree rotatable billet alluminum elbow for the block that does not leak. It's $60 shipped to your door. then you just need to pick up the filter mount you want to use, 1/2" npt to 5/8" pipe fittings and hose.
I chose to use the Perma Cool Ford FL-1a filter mount with 4 way inlet and outlet. This will allow me to install my mechanical oil pressure gage right at the filter, and simply plug up the un-used port on the perma cool mount. I also picked up blue silicoln high pressure oil 5/8" hose, its not cheap but it will never need to be replaced, I got everything except for the Canton adapter at a local speed shop for about $50.
You can see pictures in my 5.oL conversion thread. I just went to Google and searched for canton oil filter adapter.
