I have a set of the Autopal 5x7 conversion lenses on my '83 (also 5x7) and they're ok, but I would highly recommend the Hella E-Code H4 conversion lenses (
Quadratec link, for reference, they're available cheaper elsewhere) if the Truck-lite LEDs are outta your budget. I personally uninstalled a set of the Hellas on a Jeep Cherokee and installed the LEDs as an upgrade, way better. Though the Hellas are a solid and great upgrade over sealed beams. Main thing, make sure your headlight harness has been upgraded, preferably with a set of relays and a more direct current source to the lights through heavier gauge wire.
