Field Obstacle Hardware Source\Specs?

[IronMustang9]

Team 3711 and I assume a few others would like to know where we can get the exact or equivalent field element\obstacle hardware parts:

Team Drawbridge Springs
-----------------------------
This is P/N HW-00099 & HW00100 on the field diagram. A search of Andy mark or general google does not come up with anything with the part numbers listed.

Failing that, does anyone know what the spring specs are i.e length, #weight etc. Would be nice to have close to the the same springs to test with.

Sally Port Pnuematic Door Opener
--------------------------------------
Again no hits on Andy Mark for this but found this link on amazon: http://www.amazon.com/Wright-Product...rm+door+closer

This is silver instead of black.
