Question to AZL's brass, as well as any dealer

Hi Gang. When I purchased a bunch of 1st generation AZL SD70M a little bit more than 10 years ago, I found it very easy to swap AZL coupler with a MTL sample as these were simply screwed on the snowplow / pilot assembly.

I guess that's still the case with current generation SD70M.

However SDACe's snowplow / pilot assembly is rather different. I'm currently working on my sample in order to set a MTL coupler box but I'm far of beeing able to guess the result I'm going to obtain.

I would prefer to use a SD70M's sample...

My question today : are SD70M's pilot/snowplow/coupler boxes available as spare parts ? If the reply is "yes", I'd like to purchase a bunch of them...

Any reply welcome, best regards.
