Intro: Why the Right Mods Matter

If you’re going to drive your vintage vehicle — whether that’s local cruising or long-distance trips for car shows, vacation, or anything in between — there are just some upgrades you need. Or at the very least, they’re ones I won’t go without.

These mods may not make your car look better, but they absolutely improve driveability, safety, and comfort. Here are the three mods I always recommend — plus one bonus that just makes sense!

Mod #1 – Overdrive Transmission

This one’s a must for me. I want the lower RPMs and better fuel mileage that an overdrive gear delivers. It just makes sense — your drivetrain isn’t working as hard, and your cruising becomes a whole lot smoother.

Matching your transmission to the rear-end gear ratio and tire size is also key. For example, when I bought my 1936 Chevy, it had a TH350 transmission and 3.07 rear gears. That setup worked great for both local and long-distance driving. Later, I swapped in a 200-4R (an overdrive transmission with a lock-up converter) and changed the rear gears to 3.42. That combo hit the sweet spot — right in the 2000–2200 RPM range at 70 mph.

These days, the transmission choices are nearly endless. You can go with factory options like the 4L80 (4-speed), 6L90 (6-speed), or 10L80 (10-speed), or buy aftermarket versions built exactly the way you want. Manual transmissions are still an option too — and these days, they might even serve as a theft deterrent.

Mod #2 – LED Lights

Another highly recommended mod — LED lighting. Today’s LED options are excellent for vintage vehicles. They use less power, shine brighter, and give you the visibility of a newer car. For me, this upgrade is all about safety.

There are tons of styles out there, so it really comes down to personal preference. Find the look that fits your build, and light it up.

Mod #3 – Sound Deadening & Insulation

This one is all about comfort. Whether you're talking with a passenger or just want to enjoy a quieter ride solo, good sound deadening makes a big difference. Add insulation, and you keep cool air in and hot air out — especially important during summer shows.

When I bought my Chevy C10 last year, one of the first things I did was pull the interior and add both. I started with Siless 80 mil (2mm) sound deadening mat on the floor, up the firewall, and on the back wall of the cab. Over that, I added Siless Liner 157 (4mm) closed-cell foam insulation.

It made a big impact on both noise and temperature. Then I installed new carpet with original-style jute backing — which looked good and added another layer of comfort.

It might sound like a lot of work, but honestly, pulling and reinstalling the interior doesn’t take that long. And trust me — it's worth every bit of the time and money.

Bonus Mod – Not Essential, But I’ve Never Regretted It

Some folks may laugh… but it’s no joke — the bonus mod is cup holders.

You’ve got them in your modern car, so why not your cruiser? I almost always have a water bottle, soda, or something with me when I’m out. So, cup holders just make sense. And yes, I have four in my C10. No shame here!
