5 lug vs 6 lug

[70 Old Blu]

I was needing some input in which direction to take for my 1970 gmc lb 2wd. Iwant to lower the truck 2" all around, still be able to use it as a truck, but upgrade the front brake system for mdrums to discs. I have had some input from people around town on what I could do, but I was woundering if any one else has done the same. Some suggest just lowering it 2" and calling it done. Others suggest finding a 1987 1/2 ton, and swappng the front end, brakes ans suspension as a whole, taking the booster etc. Then I would need the rear alxe to match the five lug. Any info would help, thanks.

i bought a running 87 suburban 1/2 ton for $500 and swapped everything into my 67, including the the axle and complete front crossmember with upper and lower arms, not to mention a 350 motor with a 700R4 trans., so I am now running 5 lugs and have discs in the front, I did keep the power brake booster just have not installed it yet. bet money I spent on this truck. as for lowering thats the easy part, the cheapest way would be blocks in the rear and lowered coils in the front.

The only "plug and play" axles that will get you 5 lug are 71-72, which are sometimes a little harder to find. Your other option is to upgrade the front end as you describe, and get 6-lug rotors for the front. They're a tad more pricey than standard ones but if you take care of your brake pads (ie, don't run them down to the rivets), the rotors should last practically forever with a few turnings.
