If you decide to go with the Alan Grove stuff, his bracket kits come with a list of all the steering pumps that will work for you. As for the exhaust question, I cant be of much help because I am running an Industrial Chassis front crossmember that uses Dodge Dakota suspension with a modified steering column and power rack. There are many different exhaust manifolds for big blocks and you may be able to find a set that will clear whatever steering box you are using. It's a crap shoot, but you can fall back on the Sandersons if nothing else will work. You can buy a tube type motor mount that will work but they sometimes limit engine placement options. It's just as easy to set the engine where you want it and build a simple set of side mounts. If youre not into fabrication, R B's sells a bolt-in set of mounts for under a hundred bucks that work pretty well. Hope this helps.
