If in fact it was the front seal that blew out again, for one they make a retainer for it... but also one of the modifications is to drill the drainback hole in the pump bigger...and using the same bit to enlarge some other holes in the pump and its cover. the bit should be bewtween 9/32" to 5/16" (.281 - .313). The bushings are usually lightly staked to prevent the walkout that used to occur... there's also a bleed hole in that area too, but if that had been blocked up, I'm sure you would have had issues sooner.
