To many idiots I swear one guy had the specs off by .80-1.25 on my mothers Subaru, honestly if it is done right the first time and does not screw me it is worth the drive. I only trust one tech besides my brother and I with my vehicles if it is in the Oxford/Poland springs area I will be up there on a monthly basis this summer. For the 10.25 and 10.5 diff cover are they interchangeable?
Sent you a PM. I believe they are interchangeable.
