Hello Tim,for a new Sherman I'll help you with that roof.I also would like to say I pruchased a Jagdpanther from Phil last month and metal tracks,every thing arrived in perfect working order and Phil gave me a great deal,You know from the PM I suggested another vendor,but I should have suggested more than one vendor.I have purchased from Phil@rctankwars,also Steve@welshdragon,Bob@ETO has some unique upgrade parts,well have a merry Christmas I'm sure you will be satisfied with Phils service and products.Take care Blake
