Well it all started back in the beginning as J S said Although It may have not help in my case .
Those self taping 4 bolts on the bottom would not have ever came out in the first place .
Yes that was the beginning of my concerns . I had to wrestlie them out with a vice grip .
Now I taped treads and added stanless bolts . For ease in the future if needed .
Although there were also two cracks on top . On each side of the hump . Along with rub marks on the aluminum on both sides where the hoses connect .
Hindsite maybe but fiber glass may have been an option . But I got a good lessson in blacksmithing and chose to use thin alumininum and formed a 90 degree brace across the bottom and patch on the top . Also ground a tad of glass to relieve rubbing on the in & out fittings of the air to air .
That led me to search for a new or replacement as the shroud seems very brittle .
That being said I will continue the search for a replacement . Any help on that will be appreciated .
On the flip side , I spent all day today wrestling it all together . Less the expansion tank and a few hoses .
I can only imagine what kind of a nightmare it would have been if it were brought somewhere to get repaired !
Its all been a good lesson . The next time will be a piece of cake.
