Thread: need help with some old 70's 5 slot rims??

Tweet

I have a pair of 15X8 5 slot rims, which are a uni-lug, but NOT the kind with a oval slot. they have an oversized lugnut bore and a milled round recess that takes a circular lugnut adapter. the adapters were either for a 51/2" bolt circle or 53/4" bolt circle. these rims a five 7/8" holes which use a shanked adapter. the adapter had the hole offcentered hole in it, so you could aline it to a chevy or ford bolt pattern. I have just one need 9 more does anyone have any of these I will pay top-dollar for them!!!. these are NOT the offset washers. or does anyone know where I casn still get them. I will try to attaxch a pic of the one I have. thanks for any help

post pic of it, i probably have some floatin around

4 1/2" or 4 3/4" bolt pattern?

The adapter doesn't look large enough to have an offset and from what I can see the shank looks centered with the upper flanged section.

Checking with an older tire shop can many times net you what you need.

Hitting the bigger swap meets you'll usually find a lugnut/adapter guy that carries all the different lugnuts and adapters you'll need.

How thick is the hub on your wheel?

What kind of rear axle are the wheels going on?

What's the lugnut hole ID in the wheel proper?
If it's something like 5/8" or so, you can insert a bushing that's a touch shorter than the wheel hub thickness, add a thick washer on top and use a regular nut to hold it all together.

The above assumes the wheels are the bolt pattern you require.

Contact Roger at The Wheel Shoppe (503) 761-5119 he might have a line on some or know where to find them.

the holes in the rims are 7/8", after really looking at the adapter there might not be any offset in them, if not, what would have been the purpose of making the holes in the rims so big that you needed to install these sleeved adapter in them,??? any of you guy that were old enought to buy these type of rims in the 70's be able to anwser that????

I'm old enough to have purchased them, but don't know why the manufacturer made them that way.
My guess is they were trying to protect the bore in the aluminum.

One of the main problems with mags seems to be what I call "coning in" at the lug holes.
Caused by using the thin washer that comes with mag lugnuts.

Damage can be fairly severe in the oval hole 'Uni-Lugs" since the thin washers cone in, the nut loses torque and after a while the bore can be damaged.
What works in these wheels is to use the thick - about 3/16" thick - Centerline washers.
They spread the load from the lugnut and don't do the 'cone-in' bit.
It looks like your stepped washer/flange device does the same thing.

well I have good new!!!! there is a company still making the washer, these rims were either "appliance" or "et" rims, they were the only mag company that used this style of washer, will attach pics of the centered & offset washer. so if you have this type of rim you are in luck!!!!
