Hello, everyone,
I've been following this website for some time, never really posted or anything, but it has come down to the time where I must ask seeing how my question has not been answered anywhere that I could find.
I have a couple of Mini Cobra Copies, The Mini "Chobras" where purchased from fast tech, I'm still new to RBA's, and heard they where listed as some of the best to start with and I have some technical skills, so I thought it was a good idea, and so far so good, I have rebuilt both of them quite nicely, but I noticed that the tank on one is cracked after such fiddling, I know that they are not very strong, (polycarbonate), I knew this was already an issue from other users here, my question is this,
I know IBTanked sells Pyrex tubes, which I really really want to get, but...the 3.0ml cobras top shelf unscrews in half in order to accommodate a new tube, I cannot for the life of me figure out whether this is possible with the Mini Clone version, and seeing how I don't want to break my new tank that took 2 weeks to get here any worse then it already is, maybe somebody else would know if this is possible or not.
I know people have modded the wick holes, the air holes, and the cap threads, (which surprisingly was already fixed by fast tech because mine came with rubber O rings under the cap,) but no one seems to have tried a Pyrex tank replacement for the tank, I'll post some pictures so you can see what I'm saying..

3rd image is The Top Shelf of mine...
4th image is the 3.0ml Cobra Copy Top Shelf
As you can see the top shelf is a little different and I can't tell if it unscrews or not in order for a replacement tube. I really want to know if this is possible or not. I'm just starting to really enjoy my RBA and now I have run into a bit of a snag. Can someone shed some light on this problem for me.
