1. How difficult is it to replace the t-case on a 75? I've done lots of t-case replacements on 40s and always run into having to take off the bellhousing motor mounts to drop the t-case to get it off because of the crossmember. The 55 loks like that will not be an issue. But it's better to ask. 2. My brake cylinders are sticking. Any ideas on how to fix this without replacing them. Is it possible to rebuild the cylinders or is it better just to replace them? Everything is stock.
