Wow!

Eric has the perfect answer for you.

One other change not mentioned is that the hole for the key lock changed diameter in '80, or so. It went from small to large.

Or maybe the other way 'round.

If you're fortunate enough to take advantage of Eric's kind offer, don't forget that you must move your lock barrel to the replacement t-gate.

Also, keep ALL the hardware 'n stuff from the old tailgate. If the defroster grids work, I'd even keep the old glass glass -- it's easy to remove and reinstall. Keep in mind that if you have a spare part, you'll never need it. But if you don't have one particular item, that't the one thing you'll need.
