I don't think it's a huge job...You already have the w/p off. Just a few more
bolts, then the harmonic balancer and a few pan bolts across the front and a couple down the side should allow you to remove it. As far as a replacement, they are available new on e-bay, I purchased one for mine it is a quality piece. It fits 429/460...It comes with dipstick tube installed and blockoff plate if you're not using a mechanical fuel pump. Price was around $70.00
