Need a new black water tank on the 69'... best place?

So we found a crack in the tank and it also has a major sag. So I guess we replace. Before I search the net for hours, can someone point me in the right direction? Here goes the budget....

Inland's OEM tanks are expensive, but they are very well built out of heavy fiberglass and they include the fittings for the vent and toilet flange. I figured that I would save a lot of time just buying a direct replacement rather than trying to make a cheaper generic tank fit the existing plumbing. I'd make the same choice if buying again.

I took mine out and took pictures of it, measured it, Drew it on graph paper and sent it all to Inca Plastics. They made me a new one. I got a great deal. That was a few years ago. I will post what I sent Inca plastics. I sent pictures from all angles.

I have a thread on here about my restoration. It is long but covers how I redid my tank.

I have not done it myself but the plastic tanks can be welded. I guess the question is after taking the old one out do you repair or replace.

I am not an expert, but when I considered welding my old one I was informed the plastic used back in the early 70's would not hold a weld. I did not want to take a chance so I got a new one.

The crack is in the threads where the flange goes

We do have that other Airstream that may have a good tank. But most of the stuff in the thing is pretty beat, so I'm not expecting much.

Here it is!

It's going to require some extra welding to make it fit. We also got 2 Uniseal fittings so we could be flexible on where to install the vent & drain.

Is that pic the new tank, or the original? is it an "h4" from Inca?
