I am refurbing an 80s Tama Imperialstar floor tom. I have nearly all of the info I need in finding the parts I need. However, without the parts, I always have to wait to get everything to measure for the--Tension Rods! lol It "looks" like I'll need a 2" to 2.5" lug. But of course, I really can't tell yet. That's all I want. Can you tell me the T.rod length, thank you.
