well , the ole bird has spoken loud and clear i reckon.. i gooped up the splines, new seal and spedi sleeve on the pinion shaft (rtv'd). still leaks !! i'm no master mechanic, but [censored], did all i could.. so its time to replace that original one-wheel-peel rearend with a posi unit. hate to do it, but its time. next stop, parts wanted.. anybody got a posi for a 69' bird for reasonable cost ?
