C20 conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My search function does'nt apear to work. I know this has been covered but please indulge me.
I have a 68 C20 that I want to convert to 4 3/4 bolt pattern and lower.
What is a good doner axle to use? Welding is no problem. I plan to use dropped spindles (the kind made for 3/4 to 1/2 ton conversions) which rotors will give me the chevy car bolt pattern I'm after?
All replys are welcome, thank you.

C'mon help the new guy out. I've gone back as far as I can and I cant find the thread about getting 4 3/4 pattern rotors. I think it was chevy van stuff but I would like to be sure. Does anyone know the stock rear track width for half tons?

Try the search again, it has been working, and I jus tried it and it is working still.
Why do you want a car bolt pattern? The truck (and van) 5 lug is a 5 on 5 inch bolt pattern. Witht eh selection on the market today, i see no reason to make the job harder with car wheels.
As an added note, if your area has a safety inspection in addition to your emissions check, you may want to ask about making a 3/4 ton truck into a 1/2 ton truck. Better to find out now then after you've dropped the cash into it.

Thanks Longhorn,
I do have a set of wheels I would like to run and I figured if I have to buy axles and rotors and such I might as well save some money on the wheels.
No vehicle inspection in Arizona, they do have emission testing in some counties but not mine...yet.
