We had a U-Bolt break on a rear leaf spring on Dad's car, either the
Morris 8 or the Standard 10, can't remember, but both '36 vintage.
We lived next door to, and on good terms with a repair garage in those
days, and they sent out a van with a huge Polish guy who wrapped a chain
round the spring, and somehow locked it up in a way which enabled us to
drive the 30 miles home, with him following.
Those were the good old days...

Come to think of it, another factor is low-profile tyres. A few years
back, 70 profile was the norm and they played their part in the
suspension. Modern lower profiles have much less give, to improve the
handling, which makes the springs work so much harder.

Just to nitpick, are you sure it wasn't 80? After all 80 is the default
where no profile is specified.

I'd have said that 80 profile started to be superceded as the norm by 70
profile in the late '70s, with 60 and lower starting to become the norm
around the late '80s.

That depends on what you drove, if you where happy with steel wheels
155/13 & 165/13 where very common into the 90s
