I'm new to this forum, and have tried to check in various forums archives to avoid asking oncwe again that dreaded question, but either could find a match, or got different answers...So I'll ask again...Just forgive me 
I've got a 1979 K10 Chevy Cheyenne shortbed with a 4 inch lift and 33X12.5 R15 Mud King tires, which clear my front fenders plenty, so you see me coming.... Can I put 35X12.5 R15 tires, same brand, without any danger of hitting the front fenders corners with the wheels turned and suspension compressed???? I don't want to trim my fenders, and can't afford roght now a new 6 inch lift kit to replace the 4 inch kit.
I must say that I don't drive the truck off-road, this is a show truck that's used for shows and local driving. To go off roading I used my old 1981 K-1500 Sierra Classic beater...
Also, when I bought the truck, it had a TH350 with a NP203 converted to part time with manual hubs. Since I been rebuilding the truck sincve the day I bought it, I didn't play with the transfer case.... Can someone tell me the shift pattern of a NP203 converted to part time? Also, are there different shift pattern depending of the part time kit brand? I guess not, but I'm askin' just in case.
Finally, is there a better way than an other to engage four wheel drive with a part time kit? With the tranny on park, and applying brakes? Or can I just put it on park or neutral and engage 4 Hi and 4 Low????
I'm used to NP208 and late model Jeep transfer cases...
Thanks for your help!

You will NEVER compress the suspension just driving on pavement.
