Hi Andy , i would love to call you and have a chat about a couple of things , as i said i am no expert and although i have a few toys and have had a steering wheel in my hand since i was about 8 years old , im 58 now , i grew up at the coast and had buggys all my life , the first being a cut down t model ford , then progressed to a 1936 plymouth that my brothers built , with a welded up diff , and being shortened 3 foot 6 , it was a beast to drive and i beat the hell out of it for 10 years or so and not once did it ever let me down , even after putting it over a 40 foot razorback sandhill and landing on its rhs at the bottom , it just suffered slightly bent roll bars for the rest of its life , that was once of 2 times i rolled it , and never hurt it , or me for that matter , i also have a shortened vw dune buggy , road regd. that i bought 40 years ago and its still in perfect condition . i have many Plymouth questions going around in circles in my head and would love the chance for a chat on the phone sometime if thats ok with you . The fella that built the engine is known as flathead mike , ( Mike Davidson ) from Victor Harbor S.A. He has a website ....Flatattack ......he is mainly into Ford flathead v8 motors , im sure you would have heard of him , if not look up his website , he creates master pieces , that dont blow up .It cost me an arm and 2 legs , but im a very happy chappy . Kind regards . Simsy.
