hey guys i im workin on my 465/205 swap and im havin trouble gettin the correct seal from the parts house. the seal i need is the one between the adapter and the 205. it's 10 spline. the inner diameter of the 2 wrong seals ive gotten from the store have been too large. problem is...i dunno what year my combo came out of. if i knew that i could take a better shot at gettin teh right #. thanks in advance.
