I wouldnt rule it out. There is a speed shop by my house that can get custom arp bolts and studs. all i have to do is get an extended stud for the top hat. It just sounds like the studs arent long enough to go through the shock tower and gt spec tower bar. Mine shipped today, i will run them by the shop and see it he can get longer studs for the top hat when i get them
Here's one more hoping this is a realistic option.
Thanks for doing the legwork for us all!
