Driveshafts

Hi guys, I have a 69 Dart 727 with 83/4 I wanted to upgrade to a better yolk heavier duty and was wondering what is the best donor car /truck I could take a driveshaft out and have it cut down??? Junkyard build

Thank you, Mopar or no car

The car just got a narrowed rear end moved the leaf springs in moved back the leaf springs a half inch

Look at used Nascar drive shafts on ebay.

Seeing that you may live in Cali there are probably tons of rust free shafts available to you. You should be able to find a clean B-body shaft to work with

DoctorDiff can hook you up with a nice CM shaft for less than you would think

I saw the doctor diff deal I just think shipping would kill it

Aftermarket driveshaft with solid Spicer u-joints and billet steel yoke are good insurance, even if just footbraking. Used driveshafts are still old, "used" and will probably need shortening so you'll be spending some time and money at a driveshaft shop already. Might as well try to upgrade.

Call Mark Williams and Strange Engr. and compare them to each other and go from there

Mark Williams ONLY, I will never use another Strange one again

Find a local shop that builds and repairs drive shafts for heavy trucks . They can make you one. Luckily here in W Md the shop here builds shafts for the Pro Stick guys. Mine was 250 with the u-joints.

Not sure how much room you have but many trucks have large diameter 1 piece driveshafts (aluminum) you could cut down.

Local truck shop makes shafts for me also.

Yep, had a couple built at Inland Truck Parts locally.

I did the Strange deal through Dr. Diff once and it was fine, but Summit does the same deal cheaper.

the only thing that makes me apprehensive about using a place that does truck shafts, even if their work is flawless, is the speed at which the shaft is balanced at.
most [?] truck places only balance at the slow[er] shaft speed[s] a truck sees, and not the high rpm needed for a car, especially if an overdrive transmission or gearvendors unit is being used.

And the ONLY people I found that can spin a drive shaft at used rpm is Mark Williams, I threw away a brand new Strange shaft, it had a high speed vibration, called Strange & they FINALLY admitted they can only spin them 500rpm ,so did the alum shaft I had before, did all the pinion angle adjustments ECT.ECT.ECT, got a Mark Williams one built & the car is SMOOTH as glass at 130 mph
