Sorry guys I've been offline for a bit. Totdoc, warren, t bone, ken, thanks for all your input and help. I appreciate you guys trying to help me out. So yes I'm going from 8" to 7.25" tanks. Yea I know I have to get different bands. I ordered highland bands for $150 and I just found a guy that is selling me his new style dive rite manifold for $80 bucks. So hopefully this will all work out. If anyone is looking for a manifold and bands for 8" lp tanks please foward them to me as I'm now selling the set. Again thank you guys and I will keep this post going through the process of putting these monsters together.
