Frank,
I personally just remove the rollpin from thr coupler, unbolt the column from the fire wall remove the dash to column filler loosen the three column to pedlel ass. nuts and slide the column back a bit.
If you plan on resealing it and have no issues with play in the box the Parts Master output seal kit is # 8517 but I lost the input seal #. Each runs about $18
just checked Advance Auto, we deal with then alot now that they offer lots of name brand stuff at better prices, and they offer a Power Craft rebuild kit with seals and bearings for $63 part # 8539 and a complete seal kit in Power Craft for $48 part # 7895.
