Deceleration valve?

I have a 1972 Ford Mustang, 351C, 4bbl, 4-speed manual. I need to replace or reroute around the deceleration valve (a/k/a distributor vacuum advance control valve). I can't find a replacement for it anywhere. Does anyone know where to find a replacement or how to route around the valve? It is used during deceleration to advance timing to decrease backfiring.

It retards the timing on a 71?? You are talking about the dual diaphragm distributor?

No. 1972. It retards the timing when you remove your foot from the gas, supposedly to reduce NOx and prevent backfiring. It's also called a Distributor Vacuum Advanced Contol. You can see it in Fig. 113 (as number 15) by following this link.
