Looking for replacement air tank

I’m looking for a replacement air tank for my Kenworth. So far I’m not having much luck finding options. The local dealer quoted me at about $850 for a new one, but I’m hoping to find an alternative. Anyone have any suggestions?
Dimensions of the tank are 9.5”x 43”
Thanks!

 

Thanks for the suggestion! I should have mentioned I’ve spent considerable time on google, I was able to locate a used one but wanted to see if there were other suggestions for a new tank before I went the used route.

 

I ended up ordering a used tank for Kansas City, it should arrive yet this week and I’ll swap it out. I didn’t have any kick in finding a new one and don’t have a way to weld this one...I’m not even sure I’d want to anyway. In planning to swap it this weekend if all goes well.
