hello, Im new to the forum and have a question that may have been asked before, though I have not found it, so...
I just purchased an 85 K5 blazer, has 65k on a sbc 305 all oem.
Want to ask if there is anyway to swap out the electric tailgate window for a manual one?
Also, can I snatch off the Air pump without causing any problems? Whats involved with that?

The A.I.R. pump is primarily designed to lower emissions during cold operation. Once the engine is properly warmed up, it does very little. The only issue with removing it is whether or not you must pass emissions testing where you live. Removing it will result in failing the visual inspection part of the test.

Hey thanks for the reply, I am not in a state that requires such emission restrictions. Just kinda curious about any plugs or aftermarket exhaust replacements that might be necissary if I removed the A.I.R. system. Thanks again for the info.

Most people force brass pipe plugs into the holes - not the cleanest solution in my opinion. Dorman Products sells the correct steel plugs with flared seats.

Kool, Ill check out the Dorman plugs.
Would you happen to know about retrofitting the electric window key box on the tailgate with a manual crank, is that possible?
Thanks again for your help.
