Hubby just called and wanted me to ask - he needs to go D60 on the front of his '78 K20 because he keeps breaking the D44 shafts /forums/images/graemlins/shocked.gif . Question is, did the D60 come in both 3/4 and 1 tons? If so, does the 3/4 need spring perch modifications? Does the 1 ton version? Thanks kids /forums/images/graemlins/wink.gif gotta get my man back on the road so we can do some more mudding.
