67' 10 bolt 6 lug to 5 lug axles? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

67pearland · 05-12-2019, 09:44 AM

I have a stock 67' 10 bolt with 6 lugs & wanting to convert to 5 on 5 lug. Also going to disc brakes. The issue is finding the proper axles for 30 spline Left side of 29-9/16" & right side 30-9/16" length.
I see the 12 bolts but can't seem to find the 10 bolts.

The issue you are having is they did not come with a 10 bolt. You will need to ID the rear that is in it. Best thing would be to find a 12 bolt for the truck.

The only 10 bolt available in '67 is the Dana 44 which came in the GMC's. There would also be leaf springs instead of trailing arms and coil springs. There are no 5 lug conversion axles for the Dana 44. Switching to a '73-'82 truck 12 bolt or '79-'87 10 bolt would be the best option for 5 lug axles.

Thanks Y'all
that is what I have, a GMC with leaf springs. Well not I guess I need to find a newer rear end or stick with 6 lug. I wanted to go with rear disc, not sure if that is possible keeping the 6 lug.

I make two different 6 lug rear disc conversion brackets for the GM truck 12 bolt and 8.5" 10 bolt but nothing for the Dana 44.

99-up Silverado rear with factory disk brakes and parking brake . Cut off the stock. Brackets and weld on a new set and bolt it in to match the 6lug u got . 14mm studs in them for the wheels .

I believe the '99 and up differentials are about 3" wider than the '63-'70 differentials.
