actually a good amount of em in junkyards up here
i have the front crossmember from under the firewall but no the smaller front/front one i dont have

radius rods id buy new if i were you, they like 60-70 each i had to replace the same parts as you about 2 summers back when i did somthing similiar. I got the front firewall crossmember lying around because i found a 4th gen partly stripped behind this warehouse near me and i took the entire suspension and shit off of it to repair my car. only thing is i got 2 bent radius rods from the junkyard in a row, so i just bought new ones instead.

good luck with that man, the #4 piece is only used during initial shipment of the cars from Japan, its used as a tie-down.
