I originally had a Griffin 19 x 26 Alum NASCAR which worked fine for about 1.5 years but developed a leak in a weld. I got it from Summit for 189.99.
I recenly replaced it with a 19 x 26 custom aluminum from Afco Racing with no filler, two AN fittings and a drain petcock for 255.00. Very pleased with it and it looks like a bit better quality than the Griffin.
