I want to convert my powers teering to manual steering. I need a manual gear box, was that available on 73 lesabres and centruions? Im removing the power brake booster too, just bolting the master cylinder to the firewall where the booster gooes. I think I needed to shorten the plunger rod. Both of these mods worked greeat on my 66 Chevy Impala and I want to do the same on my lesabre. When I get rid of the power steering, Im going to get rid of the SMog pump too because the bracket attachest to the ps bracket if Im not mistaken. Please advise if this is possible. Thanks Gary
