67 c-20 rear end 5 lug conversion

[ramses69]

What is the best year 5 lug rear end to replace the one i have on my c-20?

[graymond1967]

I would change the axles and brake drums. Probably the cheapest. Unless the rear end is toast.

Thank you for the reply. Sorry for the noob questions. What axles should i replace them with? Is there a quide on how to do that?

If your truck is a c/20 it should have an 8lug front and rear wheels. to change to 5 lug. everything will have to be off of a 1/2 ton with 5lug running gear.

Here is one conversion kit for your truck.

You would need to do the front to go to five lug as well, I am assuming you have drums,

You might have to change the spindles on the front but this may be a good opportunity to go with dropped spindles. I "think" that the front suspension from a newer truck may work on yours. 73-87.

These are a guideline, you may wish to crank up your search engine and find other conversions. Car 5 lugs are different than truck five lugs.

Cheers.

The Rear conversion you are showing from Speedway are not for a C-20... That is a C-10 conversion... THe Dana or Eaton C-20 rears will not allow this type of conversion... there is no way to convert the Dana or Eaton to a 5 lug not to mention it is ALOT more cost effective to locate a 67-70 Rear if you are concerned about keeping the narrower track width or go to the 71-72 for a 1.75" wider track...

[ramses69]

It is a 8 lug rear end. What year axles would work on that rear end or is there other year trucks that have rear ends that would fit?

On a C-20 running the 8 lug reared you are stuck with the 8 lug axle... even if you could change the axle to a 5 lug (which you can't) you would not be able to find a brake setup to fit.... Again the most cost effective way is to locate a C-10 rear differential...

I have a dana 60 under mine with 8 lugs and would like to go back to the 5 lug wheels.

I would suspect finding a 67-70 rear could be difficult. Is there another rear, possibly with a limited slip, that would work with this truck? I assume that brackets would have to be welded on.

There are alot of options out there but these differentials for the C-10 are everywhere especially if you are good with a open carrier and not a P-trac... you should be able to find a bolt in application for 300 or less with the brake drums and all...

Anyone now what it will take parts wise to change the front to 5 lug?

[Elliot949]

Spindles, and brake...

I bought an 84 Suburban complete for less than $500. Pulled the front axle complete out and slid under my 1/2 ton frame. Drilled two new holes and elongated 2 (one each side). Instant 5 lug and disc brakes.
On the rear pulled one rear end out slid the other (5 lug) in place and installed. Used the u bolts off the donor (if I remember right).
Anyhow, buy a donor and swap em out if you want to do it on the cheap. If you want all new stuff, the new (donor) stuff can be rebuilt from any of the auto supply houses. MOOG is good.

Thanks guys! IMO why do you want to go backwards?? It's a truck haul something!!
