There are two kinds of GMT400 owners: those who've never had this happen and argue that side posts are just fine, and those who've had this happen more than once and went top post. I won't even argue with side post proponents - their time will come. Just know that top post is the option if you never want this problem again.
I guess I'm a hybrid, then. I had issues with the sidepost until I figured out what I was doing wrong. I do not like top posts because they always seem to be corroded, and I hate the lead ends on them. The exception is my Volvos (yes it's plural now) they've goy some really nice terminals, which may not really be Volvo, but European.
