This boot,the two 9751 kits purchased earlier and the HPR0100 purchased later worked great in building the cold ait induction system on my 1960 MGA Coupe and replacing the older heater duct hose on it also. I am very pleased with the products. I would attach a photo of the completed system but don't seem to have that option here. Tom
