Basically what I need for this conversion? I know for the front wheels I'm going with Disc Brakes, but what about the rear? Am I going to have to change the rear end to change the lug pattern? Are there any other solutions?

Thanks, Needing ideas for upgrade i would like to have some good looking 5 lug rims

I believe that CPP and other vendors sell conversion axles that will fit your stock rear end

Conversion axles from CPP (vendor) and I'm sure there are others too...

You could swap out rear ends for one that already has disc brakes

You could get your axle flanges filled and then retapped for the 5 lug pattern, but I can't speak for how safe it is, and I cant think of any welder/machine shop who would warranty that

You can also just get 6 lug front rotors and not boher with the five lug conversion. unless you want some wheels that only come in 5 lug.

A conversion kit would be the easiest solution, but if you prefer to redrill, post #3 on the following link may be helpful. I have a 1960 GMC with a Dana 44 rear axle and didn't want to change it. I not only used the later 5 lug drums, I also added the later self adjusters. Did the change about 10 years ago and works fine.

I'm not sure about the redrilling I'm more inclined to get the axle conversion. but I may ask about the redrill at a near by shop.

I've also heard of an adapter for the front, does anyone used these before or have any ideas about them. Where also can they be founded. Thanks

Dont like adapters myself. You would also have to account for you adapter thickness in you wheel off set.

Here's a source for adapters, but I also don't recommend them:

http://adaptitusa.com/

I carried one with my spare tire for about a year when I had a 6 lug rear and 5 lug discs up front. I never did use it, and after I redrilled the rear axle I threw them away even though they cost about $100. I didn't want to be responsible for anyone else having a potential problem with them either. I suppose some 5 lug adapters converting from one pattern to another may be okay, but with the 6 lug adapters one lug stud always overlaps and needs a special offset stud. It's just something I wouldn't want to risk my life on for a daily driver.

Not sure what look you are going for, but I ran into the same problem on mine, 5 lug in the front 6 lug in the back. I opted to go with old school wheels from here: http://www.thewheelsmith.net/chevy_wheels.html

This allowed me to run 5 lug in the front with 6 lug in the rear. I suppose if I ever want to upgrade to a newer style wheel I will be back in the same situation. I was going to buy new axles before I found these wheels.

Thanks for the info and links, about the converter kit and adapters. I'm thinking about staying away come the adapters though.

My 6 lug rims have an chev bowtie center cap. Which is breaking off. Where can I get these center caps? Are even different rims for 6 lugs?

I have a question on Wheels. I am changing from 6 lug to 5 lug to fit the rims that I'd like to have. I spoke with a rim rep and he stated that I'd need to measure from the center of the wheel to the edge of the front fender and then from the center of wheel to the closest edge from the backside of metal. All of this is to determine the size of the rims. In addition to this he also told me that I need to figure out whether I wanted 5 on 4 1/2 or 5 on 4 3/4. (I wanted to put the old style cragar but in aluminium) I hope to keep the stance close to stock and use tires that allow me use the truck for work, not the current fad of rims an inch away from the pavement.

My questions are these; is one structurally stronger than the other? What is best size of rims and tires for a 1966 truck? (I have a 283, 3 speed, which I hope to change to 700r4, as well as adding 11 or 12 inch disc brakes, ps, pb) What other things do I need to consider?


Another question? Is there an easy way to lack of a better word, google, a subject versus going page by page?

Again thank you to all for your help and thoughts

5x4.5 and 5x4.75 are car patterns. Truck pattern is 5x5. You won't be able to get those patterns to fit on your truck because of the larger diameter bearings necessary on the front of a truck. Rear axle will have a larger diameter center hub that precludes the car patterns also.

You can fit 8 to 10 inch wide rims on front, and 10-12 inch wide tires on back. IF you want to use larger diameter wheels (16, 17), you have sufficient clearance to use most standard low profile tires (low sidewall height).

I pulled the axles out of my 65 GMC and took them to a machine shop with a new 5 hole drum and had the old holes plugged and new 5 bolt pattern drilled. They have been running fine for 9 years. I believe it cost $120 for both axles. I now have 5 on 5 front and rear. I rolled a 73 front end under it and bolted right in for disk brakes.

Exactly what I did with my '94 C2500LD except I had them drill the drums, too, because there isn't a 5 lug drum that fits these monster brakes.
