Thanks for the support! As far as i can tell, except outer body everything is identical to 356. I have a new top and drop in side curtain from vintage speedsters, in burgandy. Floor speedster floor mats worked great too. The engine bay is much longer, about a foot atleast. Compartment ends right at the end of the exaust tips. So easy for the subaru or 911 engines. It is 4 inch square tube chassis mounted to vw pan so quite strong and heat flows through that. Plenty of room behind the grill fo a good size bolt in radiator or airconditioning to be put in. The 356 speedster car covers work really well and tight. I did take out the single port 1300 and installed a new 2180 i had laying around for the sterlings to get 3x the HP.
