Yes. By 1976, the great majority of new cars sold in North America were
equipped with catalytic converters. Cat-Cons require the use of unleaded
fuel to keep from destroying the catalyst. I thought that the Spit
didn't require unleaded until 1976, rather than '75. I could be (and
quite possibly am) wrong on this point.
I put an article in the SOL ftp archives last year, which talks about
the use of hardened valve seats in internal combustion engines. It is
located at:

I have been running unleaded fuel in my '73 Spit for most of the
last 15 years. Running unleaded has not been a problem.
