TTB Swap to Solid Axle - Dana 60?

Ok guys. I know there is info all over the web on this but I keep finding scattered and conflicting info. Here's the deal: I have a 1997 F250 HD 4x4 7.3 powerstroke (older square body). Axle code on door sticker is 39 which = 3.55. I want to swap out the TTB with a solid axle, so I'm guessing Dana 60. Here's my dilemma and questions and I apologize for the ignorant questions up front. I've never done this.
1) I can't find a 3.55 front axle in Dana 60 anywhere. Does it have to match the rear 3.55?
2) What is the best year models to target to find one?
3) Anyone have a good source for one? Complete assembly ready to go.

I appreciate the help.

It doesnt have to match gear ratios, but you can only use it if you start spinning as it will bind with the different gear ratios, 3.55 are out there my 94 f350 has 3.55 in front and rear, 95 to 97 front is your best bet as the brake calipers are the same as what you have now 94 and older use different calipers and a slightly smaller rotor, then in the 80s some use king pins instead of ball joints. Good luck on your build it's not gonna be real cheap to do.
Honestly when I had my 95 I never had any issues with it, but I rebuilt all the bushings with poly bushings and it made a huge difference. Just a thought.
I have 3.55 gears and had 35s when I first bought my truck and a crappy 4 inch lift, I never really had any problems towing, the only issue I had was starting from a stop, that required a little clutch slippage but that's only with heavy loads around 10k lbs, once out and rolling it was fine, I'll never switch to 4.10 in my f350 just because I tow like 20% of the time and I have no issues and when I'm empty the 7.3 humms right along at about 2100 rpm at 70 indicated, I have since lower the rear back to stock height and just leveled the front and run 33s. 3.55 are the way to go for me. And dana 60s are out there. Good luck.
