I ordered a couple pieces of 6063, 3/8" X 3/4" aluminum bars from ENCO (use-enco.com.) They are exactly 0.750" wide, and fit my saws miters slots "like a glove." But they only come in 24" lengths. Enco item # 240-2401. Enco also has dial indicators and points sets on sale in current sales flyer. To sweeten the deal, free shipping is available on orders over $25. Code for free shipping is FSCSEP. Enjoy!
