I have three sets, all of which were working when they were removed from my various 780s over the years. I'll sell you a set and if for any reason they don't work, I'll send you another one. Send me a PM

I have an engine for sale from a 1989 Volvo 780 4-cylinder turbo (long block). The engine ran well when removed a few years ago with approx. 200k on the clock.

Cash-and-carry. $300
