Old 620 wheels on new 620?

[Bleach]

Do the 14" stock steel wheels from a 1973 truck clear the brakes on the 1978-79? I figured they do but I was curious if anyone has any personal experience with fitment.

[Bugeye]

Im not sure if they will clear or not, but I know that the 73 wheels aren't vented

right. The wheels I am talking about are not vented. I dont' think cooling effect is a concern though.

[Bugeye]

hope this helps ya bleach

 

here is a wheel from my 79, notice the offset and the vents

 

here is the wheel from my 73, again notice the offset

 

this measurement is taken from the back of the mounting surface to the outside edge of the wheel on the 73 wheel, its 4 1/2 inches

 

the 79 wheel, notice its 5 1/4 inches from the mounting surface to the edge of the wheel

 

So without jacking up the 79 and taking the front wheel off and the looks of these two measurements, the wheels would fit the rear end with no problem, but would hit the calipers in the front. I hope this helps you.

the 73 has drums all around, i concur, the wheels would rub on newer trucks, the measurements alone show it, and i don't think u want to run 1" spacers :lol:

I could be wrong but I seem to remember Doug saying there were 3 different rims for the 620. The '78-'79 would fit the earlier but not the other way round. The offset would indicate the earlier trucks had a narrower width rim to rim.

The caliper sets inside the wheel though. The clearance issue should not be with how far inward the wheel lip sets but with the curve of the wheel from the lug mounting point to the welds on the rim. The shape looks the same to me.

 

The offsets show that the 1979 wheel sets inward on the suspension more which makes sense because the later trucks had a wider stance.

 

too bad I dont' have a 1978 truck to try these wheels on :)

I will rent you my truck so you can test fit them :D Why are you wondering?

[Cuts metal like mad]

jus my opinion, but if hey work on kingpin trucks with a disc brake conversion, I don't see why it won't work on a 78-79 balljoint truck

I have these wheels for sale, and someone with a disc brake trucks wants to know if they'll fit.

Can I rent your truck for a dollar? I'll need it for about 20 minutes.

Ive got a 78 620 with disk brakes on the front and ive been running it with rims off a 1976 620 for 3 years now. No rubbing issues on them.

[datzenmike]

Are the fronts wider set than the backs?

[Bandit240]

I dont know. I really never looked to see.

Early 620 wheels fit on a late 720 if that helps

[tdaaj]

i don't think you have anything to worry about. they all fit. i had a 79 truck that i run to hell and back several times. used any wheel that held air, 521, 520 620 didn't matter.

[rat tail dragger]

the rearend in the 79 is wider then the 73 about inch or so wider but i ran my stock 73 wheels on my 86 720 and they didnt rub now if you put fronteriers on a 73 wont fit unless you use a 1 spacer in front and change the rearend to a 79 if that helps
