Those lights have been around for a couple years, but you can't find them by searching for "Chevrolet truck lights" or anything similar. You specifically have to search for H4703 LED lights. And most people forget that that's the designation for those old sealed beam lights.Where have you been since forever? I never knew those existed!
The other issue is acquiring the mounting brackets for those lights. There isn't an abundance of used 88/89 quad sealed beam mount brackets out there, and reproductions cost on the order of $200 per side. That's $400 in just brackets. Add to that $180 PER PAIR of LED lights, and you're $760 into new headlights (assuming you do all 4 as LED) before you even started hacking at the wiring to get the right connector in there. This is why I haven't taken the plunge.
I recently found a complete pair of used quad sealed beam brackets on eBay for $180, so I'm still considering it...
