I know I saw somewhere that a guy hooked up the original column to the S10 steering box. Anybody remember where or what parts you need to hook the two up? I believe it was all over the counter universals.
U joints and such can be bought with differant female ends such as round for old column shafts cut down , splined to go right on gear bix and double D if you want to adapt the colopsable portion into new shaft . I think flaming river has a shaft portion that you can put in , it may colapsable and adapt two differant compents like yours . Summit jegs ebay etc should be able to find them but these may be best bought at local speedshop if possible incase you need to exchange or take you piece in to match up sizes .
