Description
1973-1987 GMC long wheel base Truck <
On the 73-87 GM Trucks there were two variations of the bed to frame bolt pattern.
One that used the two front holes and some that used the first and third Holes.
Beds with the two front holes use 8 short bolts and the ones in the first and third holes use six shot and two long bolts.
Our Bedfloor only has the two front holes in them. If your bed or frame uses the first and thrid holes you would need to drill the second set of holes in the frame and would need to two short bolts to replace the long bolts.
