The Story of Original Parts Group’s 1966 SS 396 Chevelle

Why the Original Parts Group’s 1966 SS396 Chevelle has so many rare options will forever remain a mystery. When purchased from the proverbial “little old lady” from San Diego, the Chevelle was a real SS 396 originally built with the rare and desirable L34 360hp 396ci option, but what a heap. Rust, missing parts, and body damage made it a project, not for the faint of heart. “It was so bad I didn’t know whether we’d even try to restore it,” says OPGI owner Dave Leonard. “We parked it in the warehouse and went on restoring other, easier cars.” It sat there for years.  Read more ›

Watch: Project 1964 Corvair Spyder Convertible Top Mechanism Test

It works! The Corvair Spyder convertible top is a separate mechanical system like brakes, air conditioning, or the engine itself, that needs to work at the push of a button. Tom and Doug installed a new electric pump, ram, and lines along with restoring the top bows. With it all hooked up and back together it was time to test, and to circulate and bleed the fluid for proper articulation. Here’s a video of the first test with assistance from Bob. Read more ›

Watch: Project 1964 Corvair Spyder Convertible First Engine Fire Up

A lot of progress has put the OPGI 1964 Corvair Monza Spyder within completion for its debut at the 2018 SEMA Show in Las Vegas the end of this month. With the engine all hooked up Doug and Tom fired it for the first time which you can watch here. They have since discovered a small gas leak and malfunctioning coil needed correction before fine-tuning and adjusting the valves. Still, it fired up and right on schedule.

The small pieces of blue tape scattered around the body are small paint imperfection identification as the Corvair was headed back to the paint shop Read more ›

OPGI Cadillac Spring Summer Series Show–Last One for 2018!

Each one of our five Summer Series shows was unique and presented a few surprises. Our final show featured Cadillac, and while we expected a nice mix of Caddys, the sweet spot was late-1950s-1960s models—especially convertibles. Surprising because ‘verts rusted much quicker since they leaked (even when new) and once the tops rotted they became exposed to the elements. They made fewer convertibles than hardtops and sedans, too. And these have the most trim so they can be difficult to restore without having a complete car to start, or a tall wallet. Read more ›

Project 1964 Corvair Spyder Convertible: Small Tasks, Big Progress

Have you ever done a BIG car project? There is that point where you’re working on it every day spending countless hours but it doesn’t look like anything is going on. You know, running brake lines, wiring, plumbing the gas tank—after a couple of weeks, it doesn’t look like much progress. That’s where we’re at with our project Corvair Spyder convertible we plan on bringing to the 2018 SEMA Show in Las Vegas. Tom and Doug are moving along fast screwing it all back together, but it’s a little hard to show in pictures. Nonetheless, we’ve included some progress images and even a quick vid of the front end being reunited with the chassis, or more accurately reunited with the body tub. It’s close to getting the engine/transaxle stabb Read more ›
