I removed the weld nut there was 4 spot welds on pass. side.
There was 6 spot welds on drivers side
I center punched from the bottom to locate the position
for hole to be drilled in the front center bolt.
The weld nut is there for these bolts on both L/R side.
Next is a repeat on driver side.
Well maybe a little different.
The hole to be drilled in picture below (the red circle with the dot)
Has to be drilled thru the floor-pan brace also.
I will show that in the next posts.
