Help... What to do?

Well I just developed a nasty crack in my exhaust manifold on my 71 Jeepster. Drivers side manifold has a crack about an inch long. Anybody know where to get one of these? Im really in a bind as this is my daily driver.
Ive got the 225 oddfire v6.

 

Is it a front dump or rear dump.

It dumps out the back at an angle.

Ive heard that there is other cars that I can use for a donor? Anyone can point me in the right direction? Anyone have a spare that they can part with?

 

Anything early to late 70's GM/Chev/Olds/Pont rear drive with a 231 Buick. Trying to remember the cutoff year as they enlarged the exhaust ports on the 231, early 80's I believe.

 

If you have a hard time finding a replacement, any decent welding shop should be able to heat it and weld it with nickel rod.

 

That rear dump manifold is hard to come by. I have welded manifolds before usiing my stick welder and cast Iron rod. Just drill a small hole at each end of the crack to try and stop it, pre heat manifold and weld. I have not had a problem yet!
