What is the shallowest cast 727 transmission pan I can get.

Many of the fwd cars use sealant on the pans. Silicone.
I have done hundreds of trans filters, if the pan gets a nudge, its gonna leak. If the pan is too close to the road, there is nothing thats going to fix it.
Cheap sealant is not worth the tube it comes in.
If i use a gasket,cork,paper or composite, i bond it to the pan with a contact type adhesive. Clean and dry.
