Newbie Question

Hi guys. I am new to both classic trucks and this forum. I am also not much of a car mechanic (yet), but I have pretty good mechanical knowledge from motorcycles. I want to apologize in advance if any of this info doesn't sound quite right, most of what I know about restoration and classic fords is from the net.

I'm a few days from returning to the states and have some end of deployment money to spend. I am looking at getting a 5th gen f100 in 4x4 that runs and drives, but needs work that I can do in increments to eventually make a nice custom driver. I have a source for a 67 long bed that pretty much fits the bill for what I want, with the exception of a manual trans. The owner states it may need trans work (but the price is good). The guy is working on getting the engine specifics, but for the time being, my question is this:

Can I replace the trans with an readily available automatic (say a rebuilt c6) without too much effort or customizing (at least more effort than just rebuilding the current manual)?

Thanks!

Find TP Daniels thread on rebuilding his F-250 converting to an auto. A bump F-100 will have the single speed Dana 21 transfer case. Best to convert to a NP 205 whether divorced or married case. As it came with no auto it is work to convert. Also a 67 came with the 352 which is basically the same block as the 360 and 390. Remember the ditty, a 390 on sale day, a 352 or 360 any other day. Remember to do a stroke test to confirm the engine size for an FE engine.

Excellent, that is pretty much the info I needed! Thank you! Just for my awareness, what do you mean when you refer to a "bump f100"?

I think I might just have to purchase this truck and start a build!

Bump side truck is referring to the 67-72 model year f series. Got that name due to the raised out bump on side of the body line. The 73-79 are known as dent sides since they have a inward body line.

Yep. And the 61-66 are called slicks. 80-86 are called bullnose. You'll pickup on the slang pretty quick.

A 4wd 67 F100? ...a Ford 9-inch in back and a Dana 44 in front.

If your going to use this truck for just light off roading dirt roads then an auto trans is okay. But any type of hills/mtn. type 4wheeing then you should keep it manual trans.

It's no fun if your on a hill side an the motor stalls and you can't stop or restart the truck motor and your sliding side ways out of control when you hit the brakes as this locks the wheels up.

You will wish that you never changed it to auto trans as your butt becomes inverted to a place it's never been before.

With a manual trans at least you've got gears to keep some kind of control over the vehicle even when the motor is not running , plus most likely you'll get the motor restarted just by having it in gear, where as with an auto trans you may not get a chance to try to restart it as you'll be just trying to keep it from crashed or rolled it from not having any control what's so ever.
my +2cents
Plus thank you for your service

That does make sense and I appreciate the input. I have been less and less keen on the idea since I first asked that. I think I am leaning towards leaving it as a manual now.

I may be on little bit of information overload with this forum. I am so close to being back in the states that I have pretty much nothing to do, so I have been spending my time planning my build.

I have pretty much nixed the idea of swapping in an auto trans in the immediate future, deciding to concentrate my efforts on PS and disc upgrades instead. I think I have the idea for the PS, but I am still a little fuzzy on the discs.

Ford_Six states:
For 4x4 trucks, there are a few different ways to go. For F-100 trucks, you can use GM D44 outers, rotors, and calipers.
I guess the problem is I don't know enough about the actual axle. What makes a Dana 44? Are they all the same out to the knuckles or how does that work? When he refers to "outers", what is that? I have tried to find a diagram online that explains the parts of a D44, but no luck.

Once I figure out what outers constist of, do I just need to find any vehicle that uses a d44 and has disc brakes to rob parts from?

I appreciate the patience. I usually try to avoid forums because of attitudes, but this one seems to be different.
