Linda, There isn't anything new in bolts. AN bolts are still the same but I have found the parts book is not always correct in the length it calls out. On the screws the main difference is that the Ercoupe came with straight slot screws and most people use Phillips today so it depends on if you want original or not. The straight slots do cost more these days. The parts book does call out stainless screws for the hinges and panels (cowling, fillets, tail cone etc). It does not show washers but they are a good idea to keep the paint nice. Plastic ones could be used or thin stainless steel ones work well also.
