The ones on my '68 Dart were just radiused. No spring offset, no tubs, nothing fancy. Things were a lot easier back then, you just did what you had to do to make it work.
If you have 10" brakes they will work fine with no hassles. If you have 9" brakes the edge of the adapter barely touches the drum balance weight. Not much, but enough to prevent the adapter from seating squarely and they will loosen up while driving. A little judicious grinding may solve the...
Sorry, 8 3/4" axles won't work in a 7 1/4" rear end. From 1973-1976 disc brake equipped A bodies had 7 1/4" rear ends with big bolt pattern brakes. Unfortunately, the axles are too short to swap into your current housing so if you want to go with that, you will need to swap a complete rear end...
You can use the 100mm wheels if all you are wanting to do is roll it around the shop. My Valiant came with one as a spare when I bought it. The wheel will go on but it won't tighten down enough to drive safely.
Coker has the Firestone Wide Ovals. Why in the world you would want them is beyond me. Wound up going backwards in the rain too many times to ever have another set of Polyglas tires.
As Mopardeacon said, the adapters will hit the balance weights on the drums and cause all sorts of problems. The good news is that this is only a factor if you have 9 inch brakes. The 10 inchers clear with no problems.
The wheel maker probably used 13" centers. They are a lot easier to find. Know that 14" SBP steel wheels cleared the KH calipers since that was what was on dad's '72 Dart. Summit has wheel spacers but the closest bolt circle is 5X100mm. They will go on a 5X4 but they are a few thousandths...
Wore out a bunch of Polyglas tires back in the day, and I would have to say that compared to what is available now they are absolute rubbish. I wouldn't use one for a spare. They may be OK for a trailer queen, but I don't own any of those.
Won't work. The .060" difference puts a side load on the studs and causes them to break. Drilling the holes out a bit makes the wheel easier to put on the car but the taper on the seat and lug nuts puts the same strain on the studs. Learned this the hard way when I tried to use the minivan spare...
Some 411 here. Car in your avatar? Make it or buy it? If ya made it, parts ya used. Could be any number of things that could be fixed for a little of nothin. Let us know.
The studs you need are NAPA part number BK6413148 for RH and
BK6414089 for LH. The RH is head stamped 130 and the LH is head stamped 131. Overall length is 2" and the shoulder length is 1 1/16". with a 7/16"-20 thread size. Hope this helps. :thumbup:
If it will help any, these rims were on a 71 Sport Fury wagon that I once owned and on a 77 Newport that I bought new. My guess is 69 or 70 to end of production C bodies with full wheel covers.
