QA1's GM Pro Coil Systems are available for 1963-1982 Corvettes and for 1958-1970 Full Size Chevrolet vehicles, including Impalas, Bel Airs and Caprices.

Check the size chart and reviews!
Color: Black, Size: 3X-Large, Color: Black, Size: 3X-Large
Bought this for my husband and if i didnt check the reviews I would ordered it too small. He normally wears a XL in T-shirts but he has very large arms so the 3XL in this fits him comfortably. The material is a bit stretchy so he could have probably taken the 2XL but I am satisfied with how the 3XL looks on him. He looks so good!

Size discrepancy
Color: Wine Red, Size: Small
I like the look and feel of this shirt, but I originally bought a medium and it was too big, so I bought a small. Both shirts are the exact same size. It is labeled on the collar as a different size, but it's the same. If anything the small is slightly larger

The material is good quality and it did great in the gentle cycle of my washing machine. I hung it to dry, no dryer. Looks great.

Cheap and nice.
Color: Silver Black
It's heavy and easy to wind. Time is slightly fast, maybe a minute per day. Easy to resize. Great value.
