I just received the seat for my 31 roadster from Hot rod seats. Bob did a fanatics job of fitting it to my Brookville roadster seat riser. He took the time to verify the seat riser dimensions; so when I received it all I had to do was bolt it together and set it in the riser! I don’t know about you but it seem like every time I order something custom I have to modify it to fit. I still need to bolt the bat wings on, but then again I still need everything from the cowl back! Lol! Of course it will be fun to drive around the neighborhood like it is. The seat’s comfortable! Thank Bob for the Great seat and service!!!
