In the course of changing oil on my 1987 Grand Wagoneer, I discovered that I could not get the new proper oil filter to thread onto the mount. After a dozen attempts and a meteoric rise in blood pressure, I gave up. After cogitating on it, I looked at the OLD filter, a POS FRAM filter, and called the parts house for a cross-check of the filter number. The OLD filter was the wrong filter for an AMC 360. But now it's the only one that will thread on.
Apparently, I will now need to replace the oil filter mount, insofar as the threads must be stripped to accommodate the wrong filter specification, but have not done this before on any of my Wagoneer, and so: How difficult is it, and how difficult will it be to find the correct part? Is there any other way of doing this, i.e., re-die the threads, etc.
All advice will be appreciated.
