My new totally stock 1972 K5 Blazer 350/Auto 4X4

[PGG]

Ok I joined the club after selling my 1977 FK40 which was great but I wanted something larger. I was thinking I would buy something and modify it to my liking but found a deal on this survivor super clean stock K5 Blazer. I think it needs to remain mostly unmodified and close to stock. I might want a 73-75 project that I can mess around with while I drive this for fun.
I am going to add a stereo that looks stock with speakers that are pretty well hidden away and put wheels and slightly larger taller tires on it and try not to mess with anything further. It was repainted back to the original color then put into storage for 3-5 years then I got it last Monday.
Any suggestions on slightly larger tall not too fat tires that wont rub?
Opinions on adding a stock roll bar and if it would hurt the collectible value?
I need to replace the AC compressor and hoses where to buy?
I need the rear side panels in white vinyl found them for $499 OUCH better options? I also need the mounting hardware.

Tell me what you think.
Take care Thanks PG
