Ever see 15 inch P01 Wheel Covers on a Longhorn?
I saw this yesterday and had to share. I looked at this longhorn and saw the P01's and thought that doesn't look right, 15 inch wheel covers on a 16.5 inch rim. But there it was and factory installed. The centers say GMC as well. Anyone ever seen this before? The truck is an Oshawa build Canadian 1972 GMC truck sold into Canada and the spid says " Z62 Custom Deluxe Equipment " and there is no mention of wheel covers on the spid. the serial # is TCE2421......and the model number on the spid is CE26034.... Would those wheel covers been part of the Z62 Package?

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
It looks like the wheel covers are either installed on the trim ring of the 16.5" wheel or has some type of spacer. I can see the actual hub cap is only a 15" and then it has another ring of some sort. These wheel covers were never made for anything but a half ton

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
Could it be the truck has 8-lug 15" wheels? I had aftermarket (wagon wheels) 10 x 15s on an 8-lug truck before. Probably OEM-type were also available. Wheel covers fit on most any 15" steel wheel. What size tires on that one? The wheel covers were always listed on the SPID because they were always an option.

Tire size is 16.5 You being the GMC man and it sounds like you haven't come across this before.

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
Wheel covers were an upgrade I believe and as such should be called out on the SPID. 1" spacers exist and do seem to be in use on this truck. Look at the rim of the wheel cover - seems wider but that's the spacer.

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
Because the man that is in the truck in the pic is the original owners son and was a teenager and was with his Dad when he picked up the truck in 1972 and those wheel covers were on it. Maybe because they are not on the spid they could have been dealer installed. I've never seen anything like this before and it seems like maybe you haven't either. You are the first person to state you find anomalies from plant to plant on these trucks. Have you ever seen this setup before Tim?

To me the wheelcover also appears to be stacked on a trim ring or some adapter. The edge deformation supports two pieces. Since the truck at the trim level should have had, as standard, hub caps (and not appearing on the SPID) it would seem these were added post factory. Has me wondering if in this case the truck was actually new or a demo, possibly even used. The latter two could be plausable causes for the change.

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
Here is an example period part from Ford ('72 E300 van and F250-350 trucks) that actually did just that, adapt a 15" wheelcover to a 16.5" wheel.
http://www.fordification.com/hubcaps...t/d2tz-1210-a/ So it is likely something is like this on the truck in question. However the lack of SPID reference (to me) makes it unlikely "factory". Are there any fleet equipment codes on the unseen SPID. If you are serious about the truck do a GM Canada doc package on it.

I've seen the spid and know how to read one and there are no fleet codes.

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
wow, that's just wacky! Have never seen anything like it. very interesting.. I would say that, even if purchased new and the guy you know is the original owner that this almost had to be a dealer add on. There's nothing on the SPID to indicate it was from the factory and PO1s were an upgrade option like Pete mentioned. Dealer would have had ready access to GMC PO1s lying around too. Also, the fact that the adapter ring has the opening for the valve stem - which would appear to leave the stem hidden behind a bumped out cap - and that is how these look to me (no valve stem and the division between cap and ring seems pretty clear to me) leads me to believe the factory would not do this (i.e. no exposed valve stem). But who knows. I do think it is very plausible that the dealer did this to make this truck stand out a little before the original owner ever walked through the door. So, to him, the truck came like this "new" - which it did. But "came like that new" doesn't mean it rolled out of the factory that way either. Dealers were a little more inventive back then, that's what I'm thinking - all part of the local marketing wars. That's my bet anyway, who knows!

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
If you know the family and are working with the son on buying it, I'm assuming you can see it in person anytime. Would the son care if you popped off a hubcap just to see what's underneath?

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
The adapters would have been my next guess. I have never seen them used, that I've known of, but have heard of them. No truck came from factory with PO1s that weren't an option listed on the SPID and GM didn't offer these. Even the Cheyenne Super/Sierra Grandes came with chrome hubcaps with the wheel covers being an option. Just as there is the Sliver Book provided by GM for aftermarket upfit to their customers, an item not found in there could have been added by the dealer either at the customer's request or just because they think it looks good and will make a truck more attractive. The Silver Book may have offered Reading utility beds while a customer may have preferred another brand not listed. That body could still be arranged by the dealer to be part of original invoice and financed in the same auto loan. This is a dealer upgrade just as saddle tanks were. At least that's how it appears to me with what I know.

Sadly I do not recall an RPO code or part number. They stuck with me because at the time I was interested in creating a similar setup to adapt a 14" wheel cover to a 15" wheel. K

Think this is it Keith?
From my 73-78 parts catalog. Not listed in my illustration catalog though.

Re: Ever see 15 inch P01 Wheel Covers on a Longhorn?
I'm betting the dealer had these caps from another new truck and installed them via the buyer's request. Dealers did what they could to please their customer back then from the stories I've heard from older folks that still have their rides from the 60's through early 70's. That sure is a nice truck from the pic you posted though.

Most hubcaps, wheelcovers and many mirror options were shipped loose ("loose equipment") as Keith describes. But in the case of factory provided options they would be listed on the build sheet and in most cases the SPID too unless included with another option. Base build items, like hub caps, would be listed on the build sheet but only rarely on the SPID. As example, a Cheyenne without conflicting option or upgrade shipped with painted hub caps. A Cheyenne Super shipped, again in most cases, with chromed hub caps. But neither lists hub caps on the SPID. So if you have, say, wheelcovers or camper mirrors listed on the SPID they were provided by the factory but actually dealer installed.

Having given it further thought - they could have been released for a specific combination of options (rather than it's own separate, stand alone option code). Said differently - if you got a c20 with a certain tire/wheel and PO1 then it would drive the adapter. If that was the case the part number for the adapter (and wheel cover) would show on the build sheet but only the RPO P01 would show on the SPID. K
