    is it true that I have to change the assembly and not just add led bulbs?

    Yes. Later bulbs are "captured" in the housings. You can remove them with work (they are soldered into the base), but they aren't like the earlier style where the bayonet style bulb can be removed from the socket by just pulling on it.

    There are some pics here of how I made LED for the style bulb you are inquiring about: http://s831.photobucket.com/user/dy...EDs C-K-R-V trucks 1973-1987 91?sort=3&page=1 Not sure it can be adapted to using the stock flexible printed circuit instead of hard wiring as I did.

    Note that the dash dimmer may or may not work properly with LED's, just depends on the dimmer switch...PWM is the preferred method, AFAIK there is no PWM dimmer made for the trucks however.

    Do you think replacing with later model cluster would be compatible?

    What do you mean? The entire cluster? Or bulbs from a later cluster? Neither would be worth the effort to make work IMO.

    LED's aren't all that, I only replaced mine because I was doing away with the printed flex circuit (which is the problem with these clusters, generally) and figured if I did LED's, I wouldn't have to ever remove it again to replace bulbs.

    You want to go backwards?

    No, won't work. No speedometer drive is the biggest problem, not to mention they are wired differently.

    The '90-91 cluster is the best there was IMO, no reason to change from it.

    You can just buy the LED bulbs with the twist and lock sockets for the late clusters. I just finished doing my 90.

    I have a 1990 White/gray GMC Jimmy as well. I just replaced all the bulbs with new ones from Oreilly. They're easy, PC versions and they simply twist into place. If I had it to do over, I would go with the LED types though; sure they're brighter.
