That looks great!
The bezel looks good too. I did the LED's also. What a difference it makes!
I'm with you on keeping it mostly stock with no lift. I have read here on the forum that 33's will fit using the stock wheels without a lift. However, I'm thinking they might rub offroad? Most 33's are 12.50 on the width. You can get the BFG's in 33x10.50 so they might have a better chance of fitting with no rubbing.
Your truck remind me of a 76' 2wd long bed I had. It was the same 2 tone colors as yours, but repainted solid blue just like yours.
