V-Drive and seats

Guys, MY 1971 F26 has a 318 Chrysler that turns a Paragon PV31R transmission and gear case. The water jacket in the gear case leaks. Since its cast iron I can't have it welded but I have used JB Weld. That stopped it for a while but now the leak is back. I can fix it again but would like to buy another gear case and never have to worry about it again. Does anyone have one they'd like to sell? It doesn't need to be working just not cracked!
Also, I don't have the cockpit chairs or frames. What do F26 owners use for these and has anyone added passenger seats to the cockpit area?

I have a 1972 F26 with the same engine/v-drive setup. The universal joint broke on the previous owner and broke the housing (number 38 on

Thanks guys... I didn't think you could weld cast but I never really checked on it. I've got to pull it anyway to replace a seal so I'll just carry it to welding shop and have it fixed. Shows what I know,huh!!

Welding cast is tough - and would probably mean someone would have to tak e it out, disassemble th eunit, heat it up the casting and weld it (you welding guys tell me if I'm wrong please).
If the crack is easy to get to, you might be able to braze it ... they make some nice brazing rods that you can use a torch (not propane) with ... it won;t be as strong as a weld, bu tit might seal it up ....

Well, that's what I thought about cast. The whole assembly needs to be heated to a certain temp and the cooling process was critical... At least that's what I remember from a year of welding school.. 35 years ago. Its just a crack in the water jacket. There's not a whole lot of pressure. I may try to braze it. The JB weld held for two years. Of course my preference is to replace it and forget it...
