Default Hurst competition plus

I have posted in the past about the serial numbers on factory or aftermarket 'Hurst Competition Plus' (HCP for short) shifters, and although I found a thread that seriously seems to point at a date code of sorts being in the serial number, I can find nothing to suggest a way of positively identifying the (base) shifter mechanism;

I was wondering if anyone in the know could tell me when OEM Pontiac HCP shifters went from a round hole for the shift rod/nylon bushing to a slotted hole for the shift rod/rubber bushing.

I have one nearly complete OEM shifter that I have no reason to believe came from anything other than a 1970 Firebird Formula, but it has the round holes, which it is starting to look to me was something not present on 1970 model year F-body shifter assemblies.

(please ignore the red circled serial number)


I have also noticed that some say:
(line 1) HURST
(line 2) COMPETITION PLUS
(line 3) patent stuff

Where as others say:
(line 1) HURST
(line 2) patent stuff

Does anyone know or have a rhym/reason why some say "COMPETITION PLUS" while others don't?

Thanks in advance for appeasing my curiosity

wow!?

Over a hundred views and no replies.

For the sake of clarity this is my principal question:

Can anyone tell me when OEM Pontiac Hurst Competition Plus shifters went from a round hole for the shift rod bushing to a slotted hole for the shift rod bushing?

(I won't keep bumping this, so if no one knows, that's fine)

I know that 64-67 were for sure the slotted hole so you used a hex wrench to align the shifter arms. Know little about the 68-up stuff.

I'll take a stab at helping, but I wouldn't take it to the bank because my mind does work in mysterious ways lol.
According to Pete's book (and with my apologies to him if I'm wrong), the rubber bushings (slotted holes) that were used for noise isolation inside the car, came about in 1966 on Oldsmobiles, And on Pontiacs in 1967. I can't say when they went back to round for sure but 67, 68, and 69 shifters I've owned and possess had the slots. I can't vouch for a 70 shifter. I don't know when they went back to round holes on factory shifters, if at all.
One other thing is that yours appears to be cad plated. According to his book, in early 1971 all shifters got gray phosphate, so yours appears to be in that 1970 period.
Try to contact Pete Serio who contributes often on PY. I highly recommend his book. And again I do apologize to Pete if I've misstated some information from him that is incorrect.
Hope this helps.

ok thanks guys!

I hadn't considered the plating style to identify the vintage - that's a good thought.
Maybe someone assembled this with parts from an aftermarket unit then!?

I didn't know OEM shifters had COMPETITION PLUS on them.

apparently some did, while some didn't.

I read somewhere that Camaro shifters didn't say 'COMPETITION PLUS', but I'm calling BS on that one.

I'd wager it had more to do with the date of manufacture.

Would have to have been after '74 Hurst shifters for Muncie transmissions.

Yeah, I wonder if someone reassembled yours with aftermarket ones as you said, due to the absence of slotted holes.
It appears that all shifters continued on with the slotted holes using a removable rubber grommet/bushing.

My 68 & 69 HCP Shifters had the smooth conical Tapered Chrome shift arm going into the HCPbody Shifter the same way. What way? no bolts. I never tried to removed the HURST arm.

I forget if Frankenstein Stop bolts were on Factory HCP.

Speed-shop HCP would have 2-bolts holding the HURST Arm (any shape but smooth conical taper arm) bolted into the HCP body, and frenkenstein stop bolts.

No stop bolts on the factory shifters.
