i have an emergency!

long story short. i have to be in jersey in 2 1/2 weeks for a race. i got some shorty headers from sanderson,and they look great,but the driver side doesn't fit. they sent me another one that i goot today and it doesn't fit! i need to buy,or borrow,a small block duster driver side manifold for a backup. i am on limited time since i work a four on,four off schedule at work 12 hours a day. if anyone can help me out i would really appreciate it!
