Does anyone have an idea where I can look to find a replacement NON locking cap for our 72? The key we have for the 72 we just bought is not fitting very well and we would really like to just replace it with a simple non locking type.

Pretty much any autoparts store should be able to supply one. Stant is a well known manufacturer. Last time I needed one, (admittedly a few years ago) I got one off the rack at Pep Boys. They are readily available.

Yep, NAPA, Autozone, etc. should have them in stock.

Thanks, will be heading there later today.
