[TR] TR4 Radiator Cap

[Tim I. Purdy]

The other day I checked the radiator, and just awhile ago, I am now missing
the radiator cap, good thing I have not been going anywhere, though I am
supposed to take it for a drive on Wednesday. My question, is can buy a
replacement at either Napa or Kragen, the only two parts supply stores here,
and if so, what would a reference to them that I need, a ie a certain brand or
radiator cap style, instead of mentioning its for a Triumph, as they give me
funny looks in the past.
