after I started this thread I got a standard wide vintage Mustang seat, great seat. Then after 5000 miles on it I fond I needed a backrest so I got a wide solo with drivers backrest. Big deference, now it's hard to plant my feet because it's so wide and about 5/8" higher,but I'm going to try to get use to it. Now I'm haveing Quality control problems like 'glider' said. I'm on my 3rd new seat in a row, and now I got to send this last one back so Mustang can try to fix it.
When all is done I will post about the Mustang Quality I want to give them lots of time to make things right befor I post...
