k-sport shock tube thread size/pitch

[Sanjuro]

Hi guys, I got a set of these rather questionable coilovers, and I'm interested in replacing the shock portion with some konis. this means turning up some new threaded tubes to hold the inserts. does anyone know what the thread pitch and size is for the main shock tube on these k-sport coilivers?

they should be standard, pretty much all coil overs are interchangable and intended for use with 2.5" springs, there are 2.25's but they are race only and not very common there either

yeah, I measured the spring and I believe they are 2.5" X 7", however what I'm looking for is the size of the threads on the shock body. I can get the pitch again once I track down my thread gauge, but I don't have a reliable way of measuring the diameter. it looks something like an M56, but I'd prefer if someone had hard numbers
