1969 YA SS Wheels?

[Bill Pritchard]

Another question I have about these wheels....

What type fasteners are OEM correct for attaching the "SS" center caps? Phillips head screws, hex head cap screws, or???? Is there supposed to be any type of washer under the screw head, i.e. flat, lock, or both?

Thanks in advance.... [img]<<GRAEMLIN_URL>>/worship.gif[/img]

bill, would this be in the assembly manual for the 69 camaro or chevelle?

Hi Ed,

No, unfortunately it is not shown in the 69 Chevelle assembly manual....I have one and I looked [img]<<GRAEMLIN_URL>>/frown.gif[/img]

I could pull the wheels off of my convertible and look at those screws, but the car is away from home in storage, so that's somewhat of a PITA....

I've only seen 2 Hex bolts used with no washers needed behind the retainer,originally.Obviously this is for the bolt on caps,and not the spring steel retained clip on caps used during most of the '70 production.
Becareful to not over tighten with the socket,as those pot metal threads can be stripped quite easily,especially after the cap has been re-plated and the acid weakens them.

Bill,

I believe the correct fastener for '69 is a large pan-head screw. It also had either a lock washer or captured external tooth star washer. I can check for sure on Sunday to be sure.

Incidentally, the gent that worked in the Baltimore factory told me that during the 69 production year, Chevrolet started including wooden-handled phillips screw drivers with the jack assembly so the customer could take off the SS cap with a tire change and be able to re-secure the wheel in the trunk. I don't know if all the factories did the same or not.

My 70 L34 has the YA SS wheels which came with phillips round head screws for the caps. Not sure it's correct, but have seen pics of other SS wheels with the same screws. Maybe both were used??

[Bill Pritchard]

Thanks to all for the replies.

Rick, it's interesting that the 70 assembly manual has the components of that wheel illustrated, whereas the 69 manual does not.

Phil, I would certainly appreciate any further insight you could provide. I am thinking that my convertible has pan head Phillips screws to retain them, but it's been almost 15 years since I've had them off the car, so I can't be certain about that, or if there was any type of washer used. And since you mentioned it, I do recall hearing the wooden handle screwdriver story before, although I have certainly never seen or heard of one with a car.

Mark, I suppose it's certainly possible that different assembly plants used different type fasteners, or that there was a running change of type during the production year.

Bill, not 100% sure my are original to the car. If i remember, the phillips head screws did have a small flat washer...

[Bill Pritchard]

Mark, was your 70 produced early in the model year? As Rick noted above, they went to the 'snap-on' type later in the year....I remember those well, because I had a friend who 'appropriated' a couple from a 70 SS Chevelle in a parking lot back in the day [img]<<GRAEMLIN_URL>>/shocked.gif[/img]

Who is your friend? I had some appropriated.
