Default Please Help a Park Avenue Owner!!

I have a '98 Ultra, and I have two problems. They go hand in hand, so ANYTHING that anyone can help me with would be great.
First, my motor mount is bad. It'* the one on the driver'* front of the car. I found one from motorsports performance, but it'* for the Grand Prix. They did say that it would fit the Park Avenue, but I am wondering if anyone would know firsthand.

Second, my flex portion of my downpipe is toast (from the mount being bad). The shop says it'* a dealer only item and they quoted me $400 to fix it. ZZ Performance has one, and I am wondering if it would fit my Ultra. They didn't know for sure, but they thought it would. If so, I know for sure that I would have to cut the 4 bolt flange off of the converter and weld it in. The biggest concern that I have though is whether or not it would bolt up to the manifold, and if there would be enough clearance.

I would REALLY, REALLY appreciate any help!!!

Neither the ZZP downpipe or the performance mount will work for your Ultra, I'm pretty sure.

Moving to "Other H-bodies and 3800s"

Well, I took a good look at it, and I think that a GP downpipe will work. Hoganperformance.com has one for H-bodiesm, and that one will definitely work. The biggest difference is that the w-body version is pretty much a weld in, but the H-body version has a HUGE flange that bolts to the converter. It'* $55 more for the h-body version, but there is no welding involved. Therefore, I think that I'm going to go with the h-body version.
