Attachment 6542Attachment 6543Attachment 6544Attachment 6545Attachment 6546 Ok Guys for those of you who may be interested I have completed the Prototype Adapter Bracket for Adapting The Utopia Driver Back Rest to the Mustang Fastback Tripper seat. I reshaped the backrest and had it Upholstered. The reshaping was to make it look like it belongs on the seat. The stock pad will fit with this adapter . I'm presently gathering Materials to make more adapter brackets to bring to Franklin. Of course I'll work up install instructions and dimension's. I personally think this makes the Mustang Way more comfortable. I'm not sure of the cost yet. But it should be below a $100 bucks. I'd like to know who might be interested? If know one that's ok too. I'll just enjoy mine ......................Dickie PS. It was raining outside so you get to enjoy my cluttered garage in the Photo's.
