Deluxe Seat belts C15, sourcing parts

[mtull]

I have many questions but not sure what to ask first.  My hope is the forum can help complete my knowledge gaps. 

Question: What other cars could be optioned with Deluxe seat belts like those found in the 1970 Challenger? I've seen 1970 New Yorkers with the exact same cover with white stripe and rectangular button.  I've seen pics in original sales brochures of other C-Bodies with them).

Question: What parts can be used as good cores from other cars seat belts?  The chrome latches I've seen are PONTONIER 600-1 and American Safety 444950.  The chrome buckles are stamped P-535.  I talked with other forum members with (I think) 1971 standard belts and they stated the buckle is stamped PONTONIER 600-1.

Question: Regarding my comment above on the 1971 standard buckle stamped "PONTONIER 600-1", could a rectangular button be substituted with modifying either the housing or the metal tab attached to the button?  I hope the only difference is with the metal tab.

In case anyone is interested, here are the measurements of the dual stowage clips for the front seats and the single clips for the rear seat.  The plastic part of the dual stowage clips can be found on some C-Bodies with the deluxe seatbelt option (I believe).  You just need the metal bracket.

The plastic covers found on 1972 C-Bodies is not exactly the same as those found on 1970 Challenger.  The first pic is from one found on a 70 Challenger with C15.  The second pic is from a 1972 C-Body, notice the texture along the face and the no white stripe.

The white banding on the 70 Challenger cover appears to be all the way through the part and done separately from the cover?  The original injection molding process (at least to me) seems to have been pretty involved.  I've seen the results from a few folks trying to 3D print these ... but I'm not convinced yet it's the right approach.
