[71CHEVYSHORTBED402]

I won’t swear to it, for all I know GM’s books are wrong, it’s just not likely. Anyway, I broke out the antenna parts I collected many years ago, they’re NOS, and one item is a kit. It’s been a long while, but the kit was missing a mast and? Doesn’t matter. What initially caught my eye today is the box reads “truck and not for tilt wheel”.

I did some research and yeah, there’s the reason why some trucks have fixed masts and others are telescoping. Fixed masts for fixed steering wheels near as I can tell, kind of cool. If I knew that before then I forgot☺ Edit: Forget all that BS about the tilt wheel..........Oooops

Now perhaps it gets controversial. I found my 1971 truck with a high crown cap and fixed mast. Word is nope, high crown caps combine with telescoping masts and low crown caps combine with fixed masts for trucks, period. I was going to rebuild it as I found it anyway preferring the fixed high, and besides, the mast I’m using has a twist to it anyway, another story.

So I did a little more research on the kit I have. In a nutshell, if a low crown cap is for a fixed mast, then why does this old kit for truck take a high crown nut?

Could be replacements or something like, but for what worth GM shows kit 986816 under Parts History Catalog P&A 30H January 1973 as: “use 994221, 05/72”

I might be beating a dead horse☺ See pics.
