Nice looking WH1. I've been into T Types,etc. since 1987 and have encountered and /or seen only 15 cars with the leather seats. So, yes , it is rare. I added the same seats with the console and stored the orig. seats. I am now on my 7th Turbo car, an '86 WH1 with 17,000 original miles. I am the 3rd and 5th owner and the only one who hasn't used it as a race car. Be sure to add all the body mounts as bolt through cushions and I recommend a K-B style back seat brace from the Tin Man (586-399-2410) to prevent the lower windshield separation and upper rear cracks developing. I have had excellent results with a Bob Bailey chip from Full Throttle Speed with stock cam and injectors. Spot on ; no tuning. I had to re chip with 208/208 cam ,Champion ported heads and used TT chip. slight tuning , but Eric was most helpful.
