on a 95 L67, the sc would have to come off. and I would strongly recomend him to change the LIM gaskets at the same time.
you would need..
1 */C gasket
2 injector O-rings
3 coupler (i know, duhh)
4 anerobic gasket maker (NOT rtv)
5 sc oil from the dealer. (4-6 oz.)
6 LIM gaskets (aluminum framed recomended)
8 12 pack of favorite brew
9 possibly limes, depending on favorite brew.
ps, if he decides not to do the LIM, omit #* 6 and 7.
