Identifying rally wheels

[clemsonteg]

Is there a way to tell the difference between the pre-72 6 lug rally wheels that won't work with drop spindles and the 73+ 6 lug rally wheels that will work with drop spindles (other than test fitting of course )? There are a ton of them for sale in my area and they would be a nice addition until I can afford aftermarket wheels.

There are no pre 72 ralley wheels. I believe the first year for ralley wheels on the trucks was 1975.

I understand. I thought I had read something that said rally wheels wouldn't work, but maybe it just meant that factory 67-72 wheels wouldn't work. Below are the wheels I have now, I don't think they are factory because when I bought the truck the guy told me he had just replaced the wheels and tires. Will these wheels work with drop spindles and no mods to the control arms?

You will need to mod the control arm slightly.
I have these on my truck.

67-70 drum brake steel wheels will not work with disc brakes.
You would need 71-87 steel wheels or any of the rally wheels.

Thanks for the info. What do the 71-87 steel wheels or rally wheels look like? I thought what I had were rallys :/

You have 6-lug rally wheels.
They come in 15x8 and the rare 15x7 size.

Most stock steel wheels are 15x6.5 and take a hubcab

Thanks for all the help I guess I need to read some more . Hopefully I can figure out what (if any) 15" wheels I can use on my truck with drop spindles and not trimming the control arms

Rallies on my 68,like those pictured.They have worked fine and I haven't modded the control arms.I've heard both ways so you may have to do a little grinding to allow full turns.

Don't sweat the a-arm trim.
I've been doing it for 25+ years.

I might just do that then. I definitely trust your expertise. I read a thread about potential failure with the trimming so it scared me.

Just trim the minimum to make the wheel spin and turn lock to lock at ride height.

Curious if the 15x7 version of my wheels still require a arm trimming. I like them just for the tuck factor.

Definitely.
The 15x7 6-lug rally wheels have 4" BS.
The 15x8 6-lug rally wheels have a 3-5/8" BS.

Is a 255/70 going to be too big for the 7" rim on the front with a 4" drop?

You might want to go with something more like a 225/70 in the front and a 255/70 in the rear. The trimming you need to do to the a-arms is very minor and not structural. It wont result in failure if you take off the small amount you need to stop the rubbing. Take your time and grind a little off and try again, then grind off a little more. Its easy to do.
