Funny you should ask because I JUST finished assembling the front axle.

Update 11/21. Moving Along...



Man this picture makes the axle look SUPER wide!


Here is what you will need to convert over to 8 lug:

All this can be found on a '77 Chevy 4x4 3/4 Ton (K20) - I went to Napa, Autozone, Kragen, used online vendors, and ebay/craigslist to find all these parts.

• "Big Bearing" Spindles
• Spindle bearing kit (contains spindle bearing, and the 3 seal parts to seal it to the stub shaft)*
• 3/4 ton Brake Caliper Brackets
• Calipers for a '77 4x4 Chevy 3/4 Ton (K20) - I think these are the same as the stock calipers
• 4x4 Hub and Rotor Assembly from a '77 3/4 Ton Chevy (K20)
• Wheel Bearings for a '77 Chevy 3/4 Ton (K20)
• Hub Lockouts (Original, Warns, etc - all fit just like on the 6-lug)
• Spindle nuts/washer from original "Small Bearing" Spindles fit
• Wheel/Hub Seals**
• A tub of wheel bearing grease

*See http://67-72chevytrucks.com/vboard/s...=335976&page=2 for pics and torque specs.
**When I bought the wheel bearings they came with wheel/Hub seals. Turns out they didn't fit because apparently there were two different styles of hub and hub seal in '77 (early and late design). If you search Napa's website for "Wheel Seal" for '77 K20 there will be two that come up - I needed the one without the flange.

So did you get NEW hubs? I can't find them listed anywhere in the parts store webpages.

Yes new hubs and rotors. I bought mine from Kragen but I just went and pulled the Napa part numbers for you from the store site:

'77 K20
Rotor only = NB4885677
Hub only = NB4886287
Hub and Rotor assembly = NB4886286

Mine came with the bearing races installed also.
