URGENT! Need help locating exhaust manifold

[Ray Sta.Juana]

Sorry, I forgot to say where I live, San Bernardino, CA 92410 for anyone who
wanna sell me theirs, I'll pay for shipping.  BTW, it was a stock manifold
that cracked and I have no idea why. I never washed the engine bay so it
can't be from water hitting it when hot. Any other ideas why it cracked? I
would love to swap it out for a HS header but I've got turbo dreams so it'll
do for now. Thanx again.
