I need seatbelts by thursday

[Fast68Chevy]

i have just the shoulder belt/lap belts pairs and retractors out of a 85 burb, in excellent shapoe that can be bolted in one of 67-72 trucks, but i doint know if the spade deal of the latch will go into 67-72 latch assembly or if you have access to the floor mounted lap belt stand with te buckle assembly, the blue ne sin the 74 C20 i have may work, they are in clean shape also,
