[gpres04]

i have a 1962 swb fleet side that i am want ing to put 15 by 12 ralley wheels on with a 29 x 15.5 x 15 tire with out having to modify the fram can it be done.

[CVA59]

Yes, they will fit perfectly. See my "old" thread. Of course i used a 1996 S10 Rear end also. I had 15x12 Cragar SS Wheels with 4-1/2" backspacing.

what is the back spacing on the wheels?

[gpres04]

well i was going to order the wheels through early wheel company i was thinking of a reversed ralley wheel 15 x 12 with a 7 or 6 inch back spacing. not raly sure do yall have any suggestions.

[Dinos63]

they will clear the frame but i think they will rub on the fender wells, i had a set of m/t on my panel and i had to widen the tubs ,but my truck was lowered too

[csa daddy]

dino what about the inside of the fender if layed out will it touch the tire

[gpres04]

i was planning on wideing the tubbs but was wondering what back spacing would be the best and if need be will flare the fender just enough to clear the tires if they didnt stick out to far. does any one know what back spacing would be the best.

I had 15x12 9"back space with 3" outer lip you may have to trim that fender lip on the inside, that will help getting the wheel on,

The best way to get the answer you are looking for, is to take measurements on your truck and see what will fit, and what back spacing you need. Keep in mind that those that have replied that they have done so, are using the '63-'66 frame which is slightly narrower from the rear of the cab back.

[fleetsidelarry]

like Captainfab says, the BEST thing to do is to measure what you have. The frame width difference he mentions is 4 inches per side. this means your trailing arms or leaf springs are outboard by a similar amount compared to '63-'66 models.
finally, if you have trailing arms, remember that the panhard bar causes the side-to-side clearance to change slightly as the axle move up and down.

CVA59 used a much narrower S10 axle on his '61

[fleetsidelarry]

actually the '60-'62 frame rails are 2" wider each side at the axle, 4" further back. I was too slow to edit my last previous post.

also, CVA59's S10 setup WAS on the later model. But it appears that he moved his trailing arms mounts INBOARD of the frame

Obviously, I need more coffee this morning

Larry is correct. I lined my trailing arms up parallel to the frame rails for a "Ladder Bar" type styling. Worked out perfectly. As i recall, I had about 1-1/4 to 1-1/2 clearance on the outer fender and about 1" clearance between the tire and the frame. Instead of spending tons and tons of money to get the pro street look with all aftermarket stuff. I obtained the same look for basically nothing (suspension wise). A little "southern engineering" and it is done. However, my old setup was not suitable for major HP or drag racing. I built it strictly for cruising and looks.

thanks for all the help i may just have to move my trail arms in and move my shocks to the inside for better clearence. i will check and see. is moving the trail arms in a major thing to do or is it fairly simple.

[fleetsidelarry]

I don't think it can be done that way on your frame which is quite a bit different than the '63-'66's. it wouldn't be "simple", but then again, swapping your rear end for something else isn't going "simple" either. no "bolt in"

Again as Larry stated. On your frame i am not sure what has to be done. I am sure you can figure a way to do it. It may require some fabrication but it wouldn't be anything that is too involved. I sat and thought for several evenings trying to manipulate the rear section on my truck and reuse all my stock stuff. It finally clicked on evening and i never looked back. Good luck with it. If you need any help we are all here to help anyway we can.

[Chevy Fleetside]

If you have a stepside bed then they will not clear that. A fleetside is a different story.

[gpres04]

yes it has a fleet side bed. i have been looking at it every night to try and find my best point of action. still not sure. thanks to all for yalls help.
