Cabin Heat Air Box Pictures J3

[crashrc2]

I am looking for pictures of the firewall specifically with the cabin heat air box for a 46 j3 cub with the air scope. Univar sells serval different types that are suppose to be compatible with the J3. I am looking to install item number U70422-000, will this fit correctly?
