By the way I looked at your photo again. The spots that are marked are to low. The holes should be centerlined up and down in the vertical flange. If not the 1/4 turnbuckles won't sit flat and the fabric won't lay right.
[quote author=Vortec_Cruiser link=board=1;threadid=8352;start=msg70799#msg70799 date=1070490346] I dug out my old 1970 factory manual, and see that these holes are NOT factory holes. They OEM mounting place appears to be on the 45* angled area below the vertical lip. [/quote]
your right, the holes in the scan are what I saw last night...........its' a whole new day now..........so I can't be expected to remember where the holes were
Let's make it even more interesting . Here is a couple of pics showing my hole locations on the tub. I don't know if it will show up or not, but these holes were actually punched. The metal at each hole location is actually squeezed a little bit. Just another little hint that may show each location. I checked my locations against what rick d found and they match right up.
I wonder when Toyota may have made a change in the locations from the angle area to the vertical area?
