need oil filter bolt
Consider this, the size of the feed and return holes in the block are smaller than the all the the plate holes put together that feed them is drilling really gonna help any thing?
Be aware that there are 2 different bolt used for this 90* adapter.
1 has all of the 4 feed holes in line which leads to twisting and finally snapping in half of the bolt. the newer style 71'& up has 6 smaller staggered [up & down/ zig zag] holes that don't twist and snap off.
This is what happens with the 4 hole version, I'd show the 6 hole but it's in the car right now.
