It dosen't sound familiar to me, but I'm sure whatever adapter you have will be used with the factory 205 adapter that mounts to your crossmember. There will be a seal on either end of the spline coulpling and an 'o' ring on the transfercase input splines. I replaced my seals cause I was getting atf in my transfercase, my transfercase has gear oil. I have heard that some 205 t-cases take atf; but I run gear oil in mine.
