Modifying a '70-71 choke knob to fit a '72

[sdyck]

Well, my choke knob gave up the ghost after 40+ years of being yanked on. It snapped just above the set screw.  I saw that the '72-73 know was NLA but a new '70-71 was still available, different symbole, but I figured it would still fit.

No such luck, the hole in the knob that fits over the metal tang is too small. Has anyone tride to modigy the knob to fit?  The hole seems to be deep enough but either the width or the bredth of the hole would need to be filed to enlarge the hole to fit. My worry is that it needs to be a tight fit so as not to wobble, the set screw seems to do little more than hold the knob in place.

Has anyone tried this?  Any advice?

Thanks.

why not file down the metal choke tang instead? much easier

I bought the one on teh left for the 70-71 from my local Nissan dealer.  the 72-73 (the one I need) is no longer available.  Unfortunatly 240rubber parts only offers teh 70-71 as well.

I thought about that, but it that part would be more costly to replace than the $10 knob if I mess it up.  I'm going to take a shot at filing/drilling/ dremmeling out the knob and will post my results.

Namerow has kindly offered to swap my '70-71 knob for a '72.  So it looks like I'll hold off on the filing.

Turns out Namerow and I had the same 70-71 knob so I went the modify route.

 

Used a meatball dremal grinder bit to widen the width of slot, the base widens so the knob slots needs to be filed out. I widened it slowly so the fit remained tight. Also drilled the grub screw hole to 1/8"

im very happy with the resultbut picture shows Lots of work to do on this interior

If you're referring to the little pod on the left side of the console that is usually the AC controls. Dealer add on...

I can reproduce the knob if anyone is in need of the correct one with choke on the handle.

but it wont be only 10$

Yup the switches are for air con. Compressor works but no gas in  the system. I'm eventually going to take it out.

If you remove the ac system, I may be interested in it although shipping might be kind of steep...
