Spare tire wheel well on 1964 Plymouth Barracuda...what size 14 inch tire fits?

Greetings all...did some poking around on the forum to see if I could get a definitive answer for this. The concern is the trunk cover sitting properly over the spare tire.....wondered if anyone has placed a 185/75/14 into the spare tire wheel well with any success....Does it:
1) fit in the space provided (across the diameter of the spare tire well
2) fit width wise such that it doesn't cause the carpet and board to rise up noticeably?

A couple of past posters thought that size might fit but there was no final verdict. Car is 1400 miles away or i'd confirm fitment myself before ordering tires....thanks all.
