Check out the pics. Original Halibrand aluminum 301 center section. Full floater early 1ton Ford truck axles, housings, and backing plates. The drums are aluminum 45 fin Buicks, milled. Aluminum safety hubs are old Franklands. Will fit 36-39 "wide 5" wheels. Rear axle measures 60.75" from wheel mount surface to surface. I have not had the back cover off, diff spins fine. Does not not have a spool, which is rare, and great for street use. Was mounted in an old 1934 Plymouth race car on parallel leaves. Has been sitting inside a climate controlled garage many years. Asking 1800 picked up in Central, Ohio. I can take more pics or videos upon request. Let me know what you need. 614-638-0882 thanks, Scott
