K 454 and TH400 upgrade snags

[Rede]

Hey guys.

I finally had two guys come help me drop the Gen6 454 into my engine bay after I tore the front grill/rad support/head light assembly out and I ran into a few snags...

Issue #1)
The PS pump that came with the brackets I'm using have one screw in hose fitting and two clamp/clamp on hose fittings which I was told were common on the hydroboost systems.
1 screw in hose was for the high pressure line to the steering box, 1 low pressure return from steering box and one outlet that ran to the brake booster...
Do I need a different pump that will work with this bracket setup (from a 2000 454 vortec) that has just the high out and low return lines, or can I cap the one brake booster fitting and call it a day?

Issue #2A)
When trying to unbolt the front clip/rad section, I snapped both of the large body mount bolts.
Are these common bolts or would I need to order specific ones?

Issue #2B)
I suspected a broken body mount near the front passenger corner and once I freed the rad support section I noticed that the 'ring' portion from the frame was now a large "U" shape...
Can I simply get a flat square piece of metal tacked on top and drill it for the large bolt, or do I need to do some serious junkyard scavenging?

Issue #3)
When I started reinstalling my transmission cross-member, I quickly realized that my original 4spd cross-member wasn't going to reach the bottom of the TH400-NP208 adapter I bought.
Do I need the taller adapter, a different cross member (if so, which one?) or is there a spacer that I can use to make up the gap?

I found different crossmembers and the taller adapter on this site http://www.justchevytrucks.com/truck...sfercases.html but I thought I'd ask before buying more parts I may not need...
