they were leaking b/c there wasn't a bolt in the tabs and no they are NOT bent, the pipes are randomly stuck into the collector, this was done when they were uninstalled. And you're not screwing up anything, they are fine, again they are not bent and yes there is build up and you were paying $350 for them not $450, right?
Actually they are not going to be that hard to get into place considering they all have to be removed before getting installed. Each one will get bolted separately and then the collector will go on. Either way thanks for your offer and consideration but it looks like they will be sold on Sunday, thanks for your help.
