Hey there. I’ve got a 61 2wd apache 20 that I eventually would like to convert to 4x4. I was wondering if I would be better off to keep the original 10 bolt because of the stronger hub bolted axle design or if I would be better off to find an 80s 12 or 14 bolt to use. She’s mostly going to be used for towing and hauling, with the occasional off road excursion. Also, I plan on swapping in a 250-300hp Chevy 350 because of parts availability and I was wondering if the stock 4 speed trans could handle it. Thanks for your time.

The original axle is well up to the task, the only real problem is a lack of support in the aftermarket for items such as gears and locking mechanisms. The trans will work just fine, but unless you get an adapter, you'll have to use a divorced style transfer case. Another hangup you'll have is the chassis itself. The 4x4 '60-'62 trucks used a different chassis that the 2wd trucks. The 4x4 is more like the '55-'59 is basic layout, and doesn't have the extra X member that the 2wd trucks do. I won't say it can't be done, but there will be alot of fabrication involved. Do your planning, and make sure any parts you decide to use will work. I would suggest perhaps looking for a later model doner truck, get the complete chassis and driveline. That will give you a matched driveline (look for a 3/4 or 1 ton w/full floating axles) and the option of adapting the suspension to your existing frame or cutting down the late model frame to fit your trucks body.

Thanks for the input Bill. You basically just outlined my plan. I’m hoping to find a 70s or 80s ¾ or 1 ton with a 5 speed manual, 12 bolt full floating axles and heavy duty leaf packs. The fabrication involved isn’t a problem, although I haven’t done anything this extensive I’ve been working with welders and plasma torches for years and have cut and boxed frames and repaired and upgraded my fair share of spring perches and brackets. The reason I ask about the trans and rear-end is because although I plan to convert to 4x4 it will have to be at a later date. For now I’m hoping to strip and refinish the body and frame and install a 350 just to get her on the road. And although I don’t have a heavy foot I don’t want to have to baby it when I’ve got a full load either.
