58 napco questions/suggestions

[c20pickup]

so i bought my 58 napco, the project is being put off until my 70 c20 is finished, but the price was right on the 58. my quetsions is, for the napco front end and transfer case, where can i find parts? im talking brake parts, steering, seals, bearings, lockout hubs, etc. im seriously considering going to a dana 44 or dana 60 front axle and a a 205 transfer case just to rule out breaking the valuable napco components and for the ease of parts loaction. that leads me to my next question, what can this napco drivetrain take for abuse? it a 50+ year old system that is worth money and i dont feel like breaking the pieces that make the truck valuabale, my end goal is to have the truck sit about 2-4 inches higher and to run a 35 inch tire that is fairly wide, the engine in it now is a 402 big block (unknown engine work done) and a turbo 400 trans, the end goal is to have about 400-450hp. i wont necessarily be abusing the truck but i also want to have fun with it, i want to be able to drive it to car shows and such, the most abuse it will see is driving on the sand dunes. what do you guys think, will the napco components hold up to driving on the sand considering my horsepower and tire size? and also where do i find parts for these axles and transfer case? should i just swap in a dana 60 and np205 and call it good?..... btw, if i went that route, i would keep my napco parts and not sell them becasue that is what makes the truck valuable i would just store them away

I would keep it napco and find another for horse power and sand dunes, jmo.
