Hi Bob,
Here are the measurements, as nearly as I could get them.A B E F
|-- --| \ / \ / \ / \ / \____/ C D B-C and D-E: 10 3/4"
A-B and E-F: 0.96"
C-D: 4 7/8"
A-F: 19 5/8"
B-E: 17 3/4" How the measurements work:
A-B and E-F are taken from the outside edge of the "nail head" to the middle of the bend.
A-F is outside-outside.
B-C, C-D, B-E, and D-E are taken from the middle of the bends. Now the "nail heads" were tough. Their thickness is somewhere between 0.2" and 0.25". I would err toward the smaller dimension. Their diameter seems to be 0.565", but I was measuring the "non-working" i.e. exposed dimension, parallel to the track in which they travel. (To call it a diameter assumes it is round, but if the dimension at 90 degrees to the one I measured was less, how would we know it wasn't from wear? Surely it started out round!) For comfort, you can measure inside your tracks. Mine are a loose fit and there doesn't seem to be any reason to have them any tighter. Finally, eyeballing the included angle of B-C and D-E, it is definitely less than 90 degrees - I would estimate 70. Of course the overall width is what matters. (While in there I happened to notice that the rod that holds the top ofthe rad to the thermostat housing is the same 5/16" diameter stuff.) Now as far as attaching the rod to the gas tank - as I mentioned there is a piece of sheet metal wrapped around section C-D. Its bend faces forward, and the open side goes under the lip in the tank. The two holes for the bolts are evenly spaced and the bolts themselves are 1/4", by 1" long I think. 3/4" would likely be enough if that's what you have around. On my tractor the heads of the bolts are underneath, which works well as they tend to stay put when you tighten the nuts, since the heads are contained in the deformed sheet metal. It is 4 1/2" long. I measured from the edge under the gas tank lip to the forward-most part of the bend, and got 0.885". From this I would take it that it started out 2" wide. It's 0.089" thick, and when I look this up, that makes it about 13 gauge.... I hope that does it. Let us know how it turns out. If you get it to work you could probably go into business!
Regards,
Jim
