90-91 elec. speedo in '88 K5 manual - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Before I drive myself insane trying to search for five hours on how I could achieve this, I figured I'd make a thread here.

My plan is to install a '90-'91 electronic speedometer in my '88 K5, which came factory with a TBI 350, SM465 trans, and NP208 transfer case. The original speedo has a trip odometer as well. Last year I installed a clock cluster in it, but kept the trip speedo. Now, I know that the housings are totally different [because I got a cool clock from a Saab that I wanted to replace the old broken Quartz clock with.

I also plan to [because I already have everything for it] swap out the SM465 for another rebuilt one with an NP205 T-case.

If I have to stay with the housing that doesn't have the clock, so be it. Any suggestions?
