double uni fitted to rear tail shaft
weather it be a 1 piece or 2 piece shaft
just putting it out there,
anyone fitted or herd of some or know why you can't fit one
thinking it might be possible to to put a 3-5deg shim on rear diff and double uni (same as front ) at gear box end if 1 piece or at centre bearing if 2 piece
to get the angle better to stop them flogging out so oftener
side note might help with no need to extend rear shaft on big lift if running 2 piece tail shaft
