I've been getting a parts list together to start updating things on my 1998 gtp. Upon searching for engine mounts I found these. I know they already make billet dogbones but these might be worth a look.

Picture below is for 2.8-3.1 regal and grand prix's, I inquired about ordering a set of these for my gtp. They told me they don't make them for the 3800 series but if 10 people were interested, they'd make them. I'm sure out of all the GP forums it would be worth the companies time to start on the 3800 application. I think they'd sell a ton of them. Let me know your thoughts. If people like them I'll contact the company and find about pricing and how long they'd take to produce.

Company name is MRZ-performance.
