4 3/4" bolt pattern?

ive got a set of 71-72 disc spindles for a 67.been wondering if theres
anyway to go to a 4 3/4" bolt pattern rotor.thinking maybe a large gm
passenger car rotor or rotor and spindle both might work?ive got a rearend
that would work.have a complete set of convopro centerlines that would
look nice on this truck.so many more wheel options with 4 3/4".thanks

I don't remember hearing 5 x 4.75 before, I had to go look it up. The stock Chevy 71-72 pattern is 5 x 5, and there are a freaking boatload of wheels available in that pattern.

The newer S10s use a 5 x 4.5 pattern, I think?

Just tossing this out there for measuring bolt pattern: http://www.tirerack.com/wheels/tech/....jsp?techid=92

If you're measuring from the center post of one lug to the center post of the opposing lug, you'll get a measurement of roughtly 5 x 4.75

PS - don't forget to install 71-72 balljoints in your control arms, and to use a 71-72 outer tie rod (you will probably need the adapter that CPP sells) if you plan on using those spindles on your '67

most newer GM runs the 5x 4.75 and ford runs the 5 x 4.5 bolt pattern

Re: 4 3/4" bolt pattern?

Apologies, you're right.

I dunno if it helps, but here's a list of 5 x 5 cars: http://67-72chevytrucks.com/vboard/s...d.php?t=234769

I had a line on some nice wheels recently, and I couldn't use them because they were for an S10. The guy said they had a 5 x 4.5 pattern and they were from his S10. I know he was measuring right ... this is what I get for taking his measurement at face value! (Glad I didn't drive all the way out there to buy em!!)

Someone on here has done this. I think they used 70's Chevy G-10 van front discs and redrilled the rear axles, but it's been a while since that was posted.

Re: 4 3/4" bolt pattern?

I actually just did something like this. i may be able to help you out as I might not be using the wheels I originally planned to use. I have a 68 with a 73-87 crossmember/ disc brake setup. I bought a set of practically brand new rotors redrilled for 5 x 4 3/4 from a board member on here. I had to replace my rear axles due to mine being 6 lug. I bought them from Moser and had them drilled for both 5 x 4 3/4 and 5 x 5 at no extra charge. Now comes the tricky part. I needed a set of drums from a G10 van (don't remember the year) but found out through much cross-referencing that the FRONT drums from a 56 Chevy Bel Air are the same part number. I just happened to have a set of drums from my disc brake conversion on my Bel Air. All problems solved. Hope this helps a little. Like I said, I might be able to let my rotors go to make your life easier if you are interested. I have decided not to use the wheels I was going to originally use, so I really don't have a need to keep the rotors. If not it is no sweat, I will just move the studs over to the 5 x 5 pattern on the front rotors and rear axles and reuse my original drums. (sure glad I did dual bolt pattern).

Re: 4 3/4" bolt pattern?

That sounds like a lot of extra work, hunting, time and money for some wheels. How much did that set you back in the long run?

Re: 4 3/4" bolt pattern?

Well, it wasn't really that expensive. The axles I needed to change anyway, and dual bolt patterns were not extra. The drum brakes for the rear were free, and the cost of the front rotors from a board member. It wasn't that bad really. If you need to change to 5 lug anyway and you have a set of wheels you want to use that are 5 x 4 3/4 it really doesn't cost anything extra. If you already have the wheels, it would actually be cheaper than buying a new set of wheels. The cost of the rotors wasn't much more if any (I can't remember what I paid) than the cost of a new set of 5 x 5 rotors. Hope this clears it up a little.

Re: 4 3/4" bolt pattern?

Just get rotors from cpp. They sell a kit with 5x4.75 bolt pattern. I am going to run the same kit on my truck. Here's a link to their website. Give them a call.

I don't know about the CPP kit. It seems really expensive to me. You can buy a 73 -87 crossmember for less than 100.00 and refurb the brakes for cheap. It just about bolts in. I don't know.
