Stanadyne's brand new 6.5 injectors became cheaper than rebuilds some time back, and I've run those since. College-budget David ran a mix and match rebuild set from Accurate Diesel, and they worked well enough for 60K. You might have some luck there.

In that department I am stuck. All of the common injectors are fine-thread, it's only the '82 engines that got coarse-thread injectors. So most of the options out there won't fit my engine.
I ordered 8 of these AC Delco units. They're suspiciously cheap @ $27 and $29 apiece (neither vendor had a full set), so I'll see what arrives. Maybe nobody wants the odd-ball ones? Or maybe I'll get what I paid for?

I found later injectors running $50-$80 apiece.

I hafta stick with long injectors anyways.
