Time for some tunes! To catch you up, Project Playboy is our 1988 Chevy C1500 truck that we dragged out of a random Florida man’s backyard. The truck was forgotten and full of interesting items—including some old Playboy magazines, hence the name. The goal with this new OBS project is to restore an ’80s-model vehicle with an era-correct look and a few hidden, modern upgrades to make it more reliable.
In previous issues, we replaced the original suspension with a complete coilover conversion from Ridetech suspension, thanks to the crew over at Saltworks Fab in Myakka, Florida. All four corners received new brakes, including a rear disc brake upgrade from Performance Online. Bolted to the new disc brakes is a set of 20-inch stagger-fit wheels from Schott Wheels wrapped in Goodyear Eagle rubber.
With a smooth-running street machine, it was time to tone down the exhaust sound by turning up some tunes. Because this truck has an ’80s vibe to it, we wanted the audio system to maintain the aesthetic.
With a smooth-running street machine, it was time to tone down the exhaust sound by turning up some tunes. Because this truck has an ’80s vibe to it, we wanted the audio system to maintain the aesthetic. After digging around the internet for retro-looking, single-din radio options, we came across Retro Manufacturing and its really unique line of audio equipment. With a catalog of many different looking radio faces and classic vehicle mounting systems, we had a feeling this was our company to work with. We ordered up a RetroSound Gran Prix Radio face along with a Motor 4HD Radio Motor, along with its pre-amplified subwoofer, dash, and B-pillar speakers, along with its small but powerful audio amplifier. That’s not all we did this month to our OBS! It’s funner to just dig into it, so let’s go!
