None that I am aware of. If your K20 is a 1969 or older, you will need to engineer a conversion for your closed knuckle Dana 44, or switch it out for a 1971-early 1977 large hub Dana 44. If you have a 1970, then you can switch the knuckles and all related parts from a 1971-early 1977 Dana 44.

Why limit it just to 77? I assume because of the correct style lockouts? Any 71-87(91) GM solid front axle will swap in and work for the conversion.

Ok thanks I appreciate it. I'm looking for a 1967 K10 right now but I'd take a K20 if that's all I can find. Might even have to start with a C10.

As 57taskforce proposed. I used an 88 Blazer corporate 10 bolt up front in my 67 K10 (was c10) and an 84 pick up front in my 59 now 4wd- I think Dana 44. Both 3.73 gearing.
