1. Space cross member down 1/2"
2. I can weld on a T3 flange for about $35 + cost of flange
3. Downpipe modification will probably be around $150 + flange ($29) - Garret 4 bolt 3"
4. AC lines go through firewall on wrong side.. Your steering wheel must be on the wrong side too... Fix it.
35 R .63 will work just fine but spool later than that
30 R .63 will peak at around 500 and spool at about the same rpm as you had.
