O/R X-Pipe problems

ok mustang crew, i put an x-pipe on my car.. i am getting a bad leak :bang: . it is coming from the driver's side where the x-pipe connects to the manifold. the UPR is not a great fit right there. the last time when i had it on my gt, i just used shorter bolts and that fixed the problem. my question is, what size are those stock bolts that connect the x-pipe to the manifold??? the last time i just used 2 bolts i had lying around the my garage that i found... well my gt is no more, and i forgot to get those bolts when i got my x-pipe off. so now i guess i have to go buy em... i guess i could just take the bolt off and WALK to the parts store, but i would rather just have the bolts already... thanks guys.
 
I have the same problem, and everyone is referring to Napa studs # 600-1819. I believe the size is 10 mm x 1.5 mm (M10). And, you did use the 1.5 inch piece of tube with a cone as a seal on the driver side, right? Well, I didn't.. thought it was an adapter of some sort.. I mailed UPR and asked and they tolded me what it was for. Now I have to do it all over again...
