Default Early Production '73 EGR/TCS System Parts Wanted

Looking to buy used original emission and related intake parts for an early '73 TA with 4 spd and base 455. Primarily the pieces mounted on the 492744 intake (or the very early 491244 but not on the late 494282 used after the emission system was revised in March).

Would like them in working condition.

1. Idle Stop Solenoid p/n 1997415 (this piece includes a mounting bracket)

2. EGR Valve p/n 7030878 (just need the valve, I have the clamp)

3. EGR Solenoid & Bracket p/n 1997414 (this piece includes a mounting bracket)

4. Distributor Vac Advance Valve and Time Delay Solenoid Switch p/n 1997419 (this is the one identified by a BLUE Stripe and opens the EGR valve approx 50 secs after the 1-2 shift. From what I can figure out, this was the one used with the 455. Switch 1997418 was the other one used on the 350 and perhaps the 400, it was identified by a WHITE Stripe and opens the EGR valve approx. 30 secs after the 1-2 shift.

5. TCS Switch p/n 490751 (this screws into the Muncie 4 spd sidecover p/n 335308, also used on the 3 spd trans early '73)
