" From: Tom Jennings <tomj@xxxxxxx> " " I don't know why everyone is so in love with those 70-up ball joint upper " arms. They have their problems too! their major advantage now is that parts - at least more of them - are easier to find than for the trunnion setups. " I know that the 64-69 AMX type trunnion has problems; I've not torn one " down, but there's some weird rubber part that wears badly, and I don't know " how good aftermarket urethane replacements hold up. iirc the best aftermarket replacement is made from uhmwpe. this is polyethylene with a molecular weight around 3 million - for comparison, motor oil is about 30. i have a sample somewhere around here, postcard size, 1/4" thick. it -clinks- when you drop it, very hard. it's still polyethylene-slick. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
