Help. I have a lug problem

[americanmusc1e]

6 lugs in the rear and 5 lugs in the front


My 70 C10 was a 6-lug truck from the factory. I converted it to front disks several years ago when I wasn't aware that 6-lug disk brake kits existed. I drove for years with 6-lug wheels on the back and 5-lug wheels on the front and two spare tires in the bed. Now I would like to remedy that without spending a lot


The front of my truck has McGautys factory height conversion spindles. (they use the 67-70 ball joints and accept 71-72 rotors) and 72 crossdrilled rotors 5x5"


The rear is a '69 (manufactured in 10-68) 6-lug 12-bolt. that I salvaged from another truck. It didn't have any brake hardware on it so I grabbed a nice set of 11x2.75" drums off a scrap 4x4 squarebody 12-bolt axle.

AS I see it, I have three options.

1. replace the rear axles with aftermarket 5-lug because I'm pretty sure the pre-69 axles are a different length. I'd have to replace the drums as well, and I'm not sure they made the big drums in 5-lug.

2. convert the front back to 6-lug. I'm guessing I'd need a a set of factory 67-70 spindles which I don't think I have anymore. And then I'd need a 6-lug conversion kit.

3. Leave the different lugs front and back and hopefully find a dual-drilled spare. I haven't turned up any results for a wheel drilled 5x5 and 6x5.5.


Am I missing any ways to do this? I'm getting ready to buy new wheels
