Here are the measurements for the top of the tank. Count up 5 lines on the right of the grid pattern then measure in 7/16 and mark it. This is the start of the tank. There is a photo on Facebook showing what I mean.
The first vertical line on the right measure up from the bottom of the grid 5-7/16" then to the left measure 5-15/16", 6-7/16", 6-13/16, 7-3/16", 7-1/2", 7-5/8", 7-13/16", 7-13/16, 7-3/4", 7-5/8", 7-3/8", 7-1/16", 6-9/16", 5-7/8", 5-1/8", 4-1/8", 3", and the last three numbers are measured from the left side in, 3/4", 3/8", 1/8". I had to split the top measurements to two photo's because I ran out of space on the first one.
Measure from the bottom of the tank to the top of the tank on the right hand side and draw a line to the two and you should have a complete tank pattern. Let me know if you have a problem so I can help or correct it.
The start of the tank information can be found in post 1609 of the thread.
If you clicked on a Photobucket link and it's not there try it on the post linked to it here. It's 12.30 and I'm beat and I eliminated some photos that I shouldn't have.
Steve.
