Manifold to downpipe bolts

I used a stud on the drivers side the rear bolt and nut it on the pipe flange. Then just need a nut to complete fastening it from the top. There's not a lot of room to get the nut in there if using a bolt from the top. I'm using 340 manifolds and tti 21/2 pipe, which makes it even tighter. To be truthful I hate working on my Duster compared to working on my Hemi Cuda.
