2 barrel to 4 barrel throttle conversion

I usually put 2 or 3 flat washers under the old 2 bbl mount,, to raise it, then unscrew the down-rod as far as poss leaving it sturdy,, then weld a small 1 x 1 1/2ish square of metal ahead of/onto the old cable mount,, drill a hole and notch that piece to use the original cable hold down, then mod the throttle press rod a little longer by threading a 1 in. piece of thick wall tube, screwing it onto shaft and screwing a fine thread piece into it then the carb connector ..

hope that makes sense.. I don't have a pic..
