Grab a vintage lockhart oil, around 35 bucks these days.
Mount it upside down like I have shown (something about oil draining backwards) on that ugly front engine mount.
Loosen the bottom oil delivery tube to the head, take the top bolts off, then unbolt it at the bottom to remove the tube, this way your not twisting it.
If you didnt want to install an oil cooler simply drilling out the bottom feed bolt to .140 or there abouts gets it running cooler on the top end, just reinstall it all at that point.
On to installing the cooler, get a pipe cutter and cut the tube to where your sure your connections are going to go.
Ive noticed that cutting the bottom too short leaves the connections like hose clamps resting on the front cam guide bolts.
Same thing for the upper connection but you have to leave enough room for the bends in the hose your going to use.
Not sure if theyre going to get super hot and mess up the 1/2" rubber, blow out and leave me stranded just yet.
I used what I had on hand which was some 3/8 braided hose, with two 3/8 to 1/2 reducers, 1/2 coolant grade oil hose to connect to the oil delivery tube.
All hose clamped of course.
If you wanted to make it really sharp, was thinking you could get into some banjo swivel fittings, brass y connector, stainless hoses or maybe some compression fittings.
Or hell maybe some copper if your doing that "show" chopper bit. You know you could easily drop a hundred doing all that either way.
