What front axle did Chevrolet put under the 1976 K/5 Blazer ??? The local 4x4 shop said it's a Dana 44. And if it is a D44, how hard is it to replace the knuckels ??? I got one going out, so I figure I'll do both sides at once. Also intrested in converting to 8 lug set up becouse 14 bolt FF is going in soon. This blazer is full time 4x4 if that'll make a diff.
