I don't know what happened but I tried to login again today and it accepted it. I'am sure all you guys have missed me terribly.I Have been reading all the posts but havn't been able to comment. I got two comments right now, one is I Emailed Norm Kouba at Koubalinks he said he still can't figure out how to lower the 450's with the linkage. and he's going to put it on hold for a while. And the other is I've waited for Clarke tanks to come out with their new tank for our 450's and what do they do? come out with a tank that holds three or four tenths more than the stock WR tank, I say say BFD, As others have asked can't someone make at least a four gallon tank?
