[urq] Radiator cap-off

[Brandon Rogers]

Guys-
I'm going to delete the aux rad with my new alum rad setup and last week purchased some silicon caps for the two upper fittings.  When they arrived they were thinner and more flexible than I hoped.  Other than welding (which I really want to avoid  - I'd like to be able to re-install aux if need be - if water temps climb this summer while driving slow with A/C) - do you have other suggestions?

Ideally I'd like a cap made of rad hose material.  Fittings are 1" and 1/4" - 5/16"

Thanks-

Brandon
