This 1956-1957 Chevy 4-Door Hardtop LEFT Rear Door Window Regulator is a restored original part for restoring the factory door-window mechanism. It is intended for buyers who need the correct original-style component rather than a generic replacement.

SEC Restoration Notes

These original 1956-1957 Chevrolet 4-door Hardtop right rear door window regulators have been fully restored. The door window regulators also fit a 1955-1956-1957 Buick, Pontiac & Oldsmobile. We replace any gears or nylon rollers that are broken or worn down. Often the springs are broken or the main rivet is loose causing the regulator to fail to raise the window all the way up. In this case, we install new springs or rivets so as to ensure that the regulator will work properly. When we get done with them they look and function like new.

Hard to install as instructed.
Size: 32 oz
Nearly impossible to get it in the tire through the valve. Yes I removed the valve core. Broke the bead on the tire and dumped it in. That worked great! So far no leaks. They should definitely redesign the installation method.

Been using it for 15 years! Not sure where the Neg reviews come from?
Size: 16 oz
I've been using Liquitube since around 2010. I use it religiously in my ATVs and lawn tractor tires. Since I've been using this stuff, I've never had a flat before. I've pulled out nails and slivers of steel out of my ATV tires but yet none of them lose air or go flat. I think some of the negative reviews come from improper use of the product or not enough of the product is being used in the tires. I think this come from variance in formula charts that Liquitube has had in the past on their bottles and on their website. The chart on their website wouldn't match the formula that was provided on the bottle. So I think alot of people get mixed up and not knowing the correct amount to add to each tire. Now Liquitube just puts pictures on the side of the bottle with an ounce measurement below each picture to tell people how to use it. But even that can be confusing. For instance, take the picture of the ATV that they show. Below the ATV it says 32oz. Now some people probably think the 32oz is for the entire ATV. Well that isn't the case. They want you to use 32oz Per Tire! Years ago Liquitube even used to say on the bottle to use 32oz per tire on an ATV. Now they just show a picture with an amount below it. Now you'll come to find out that the 32oz they recommend doesn't match up to the formula they tell you to use to calculate how much each tire is supposed to get. So if you use the formula provided, you come to find that it calculates out to use less product per tire than what the bottle tells you to use. So that's very confusing as well. So if you use it long enough, you'll be able to know how much each tire will need from experience. Just make sure there's enough on the inside of the tire to coat the entire inside as well as leaving a bit left over to circulate in the tire so it can be ready for a large puncture if that ever happens. All in all, it's a good product that does what it claims. It lasts for as long as the tire does and it doesn't freeze up in the cold either! 5 stars!

I literally watch my MPG jump up .3 within one tank, my mpg count after 6000 miles was steady at around 26.5 and after using this stuff and driving around for 1 tank of gas, it jump up to 26.8. I'm literally impressed!
