I 'm replacing the pass side tail light on my '93 Laredo..
After some shoppin' around, I find I can get OEM lens at my local salvage for $45 OR.. a shiny new after market one for about the same price (or as much as $100+ depending where you shop)
I know my '93 isn't exactly a classic and no one will ever care if the lenses are oem or after mart, so..
Recycle and use the salvage part (nearly 20 years old) Or the nice shiny new one (exact fit, no UV exposure for years etc) I would flip a coin, but this is more fun

 

I just bought a set of 2 for my 88 Loredo online brad new OEM for $45, I just figure it depends on what you like, personally. If you prefer nice pretty new aftermarker ones, go for them... if not, go with stock. If you upload pics of potential choices, we may be able to tell you more.

 

find a different junkyard you should be able to get em both for that Jeep with change coming.
