Thanks, Classic Pickup Supplies have these ones (we will ignore that they are for Fords?)
http://www.classicpickupsupplies.com.au/viewcat.php?main=1&cat=10039-10064-10070&item=3223The catalogue shows predrilled ones, but you can get them undrilled, this is the pricing they have sent me:
"The standard no hole bedstrip-s/s come in lengths of either 77" or 89" or 97" they are the same profile as the original pre-drilled bedstrips they are $49 ea, $55ea, $67ea.
We can also get the WOW bedstrips that have hidden fasteners that slide in under the bedstrip but they come in a set of 7pc s/s with the fasteners and they are $990 set. Now the WOW strips just look like the originals.
If you go onto our website (classicpickupsupplies.com.au) and click on the 53-56 f100 BODY,FRAME AND BED you will see a picture of the standard bedstrip."
