Arrow 4.11 3rd member Anyone?

does anyone have a 4..11 3rd member that i can borrow and swap into my 88 coil truck to check gearing requirements and performance? I know this is a long shot but hey, I will ask anyway.. The numbers look ok on the calculator but you will never know till you try it..

The Perkins is a high reving TD without huge HP or Torque numbers, perfect for a OD I would think. I will be pulling my Fairey and installing an Hi ratio transfer case very soon on mine if you're interested in a OD. If you have an OD now just baby it from 1 st to 4 th in OD and see if it is OK that way, 4.11s will be halfway between that and an OD.

Kevin, I'm running an lt-77s with a 1.2 lt-230 behind it... Not series stuff... what about a roverdrive? will they work with a 1.2?

OR any other Ideas? I just need for top speed on the road.

I thought d2's used a different bolt pattern. randy are you going from 3.5's the engine can't pull or 4.7s that rev too low?

you running 24 or 10 spline or ??

I figure if he's changed to the coil chassis, he may be at 24 spline... so the diff may have the same bolt pattern..
