Re: 81 Crew Cab Dually Build

I used a cutoff grinder a cold chisel and a 3lb sledge hammer to perform the whole rear drop! Had to cut 36 rivets, what a PITA!

I noticed you already have a burb tank. I pick my 31 gallon tank up tomorrow and will fabricate the mounts for it this weekend

Thats the tank from my Blazer its only 25 gallons and its a snug fit width wise, if the 31 gallon is anywider you'll have to trim the frame alittle,, i have 2 Burb tanks but from the mid 90's tho they are in Cali with my 96 and 94 burbs they are both 43 gallon tanks

Re: 81 Crew Cab Dually Build

Thanks for the compliment!

They are the factory size 235/85-16. I plan to run a 245/45-19 once I get my bolt on 19's. Right now the lower control arms are the lowest part on the truck so I definetly need to go with a bigger wheel.

Can you do me a favor and get me a dimension from the ground to the bottom of your frame rail (as close to the axle as possible) and then tell me how many leafs you removed. I want to drop the rear another 1-2" and need to do it with leafs even if I need to do a bag assist for towing. I know your running a different size tire so I will take that into consideration.
