Not something that I broke, but an aggravating experience of installing a water pump under astere repair conditions. The water pump decided to check out south after 3 years of ownership of my 1974 Capri V-6 4-speed. With the help of my dad, we changed out the water pump without pulling the radiator since doing so in an apartment parking lot would have been really messy. What was aggravating was that the pump involved 13 bolts, 3 different lengths, and 3 different bolt head sizes. I used the old cardboard pattern of the pump to assure the proper placement of the bolts. Job done. Then there was the failed clutch cable...and then later the failed and broken shift lever the morning before I traded her in for my 1978 Firebird Formula. About a year later, Ford had a recall on shift levers, but alas, I ditched the repair receipt.
