Exactly. I didn't mean my reply to be pointed directly at you. Well
maybe a little bit, about the tires. And I know nothing more about Lotus
Cortinas but what I learned looking at a few at an odd shop in El Segundo
a few years ago. But in the case of many of our cars we are stressing
parts way more than intended. When we find a fault we have to back off
and solve the problem, even if it costs more than we like or want.
Back in Rally days the English guys I met told me that if one had a
puncture on a stage the axle had to be discarded. No discussion. Do
it.
Axles are a weak point on the 1900 Alfas. The design is a little crude,
maybe, but the real problem is that early 50's metallurgy was sometimes
weak. Especially on Italian stuff, even the stuff with lots of pistons.
And heat treatment was expensive. We have replacement axles made from
vacuum melt heat treated blanks. I need to order another set and I'll
ask if the shop wants more oddball business before posting further
information.
