seatbelts
 

wondering why the correct seatbelt style is for a 66 bonneville 4dr this car is original it has the plastic buckles not the metal type also no retractors on front or rear is this correct for a later 66

why ??
sounds like the correct std belts for 66
do you have triangle anchor brackets .. 4 row belt pattern .... ROBBINS?? IRVING??
deluxe were steel covers
there is a date code on the belt first 2 numbers are the week ...
should have carriage push buttons ... I think 67 was first for blue GM
67 was first full year of our a body retractors....ithink,,, 68 for sure
big car might be the same....
