As the junior an senior trunk racks and hardware are quite different, so I suspect the tilting trunk rack assembly is also different. Nevertheless you might contact Gunther Hoyt down in VA (contact info in the PAC directory), some years back he had parts made to install one on his 1937 Super 8 and may have gathered some info on the junior variant. Also not sure if his as installed on his senior is based on a factory accessory or some aftermarket kit.
A pix of his and one from the original patent attached.
