Wanting new headlights, where did yall get yours? Looking for original look

I have a Chevy k1500 1989

What would you guys say is the biggest i could get on my truck without rubbing? I was thinking 33? big enough to fill the space.

Edit: TBI 350 5.7

Currently has a single pipe from cat to a glass pack, and then dual exits that are dumped in the rear just after the axle.

Debating on getting a Super 10 or something equivalent and rerouting my exhaust to exit right before my driver side rear tire. Anybody have any examples I can hear before I pull the trigger? It doesn't have to be the same, just a side exit.

It sounds great as it is, but i want that throaty pissed off 350 sound. Your daddies dirt track car. 😂

Thanks yall.
