Time to fix the hummer

[SteveGt]

I’ve finally decided to start fixing the hummer as I love the truck and don’t want to let it go. I have a few questions hopefully you guys can answer. I have a exhaust manifold leak and don’t know if I should replace it with original parts or something aftermarket. Also was thinking of getting 20 inch rims, what size tires do you guys recommend for it? 35 or 37? Also headlight seals leak so was thinking of changing front lights, fog light and cab lights to black. Can anybody recommend a brand or place I can order them from?

Thanks I’m advance for the help
