rearend swap

okay got the rearend bolted in went pretty good got to adjustbrakes and bleed them and get some shock bolts my new plates didn't come with em now my big problem is the driveshaft i bought is the right length but i was putting my yoke and ujoints on it,it had a differnt spline my joints are smaller than the the new shaft not much u can't tell by looking at it but they just fall thru the shaft so i went to the zone and advance nither one has ever heard of what i call bas#$rd or morfeydike joint i had toget one years ago i know they make em ajoint with 2 size caps anybody know who sells em i think u ought to know parts before u sell em but then again i think u should speak english before u get a greencard
