Just curious if im using Tatum 934's can I switch to something like a Fortin or Pro-AM without replacing the mounting flange on the trailing arm? kind of a dumb question I know but could I could use some help

Yes they do all have the same bolt pattern.

Yes/no... Some 934's use bigger bolts... I know that Albin does.

Zilla

Sorry I should have explained it better..Im talking about the Midboard Hub, not the CV's themselves.

They should be the same.

But then again Im not trusting anyone anymore after today.

Stub set up but just saying not everyone is on the same page.

I moved up to Monster stubs from Gear one today and bought all there stuff I had to replace my my bolt in bearing carriers. So get home and the Tatum Carriers fit only there trailing arms. The center opening on the arms are like 1/16 smaller.

But at least the hole pattern matches and the backspacing is the same.
So bust out the grinder and open up the trailing arms.
I was going to turn down the gearone bearing carriers but than I have a Bastered set up.
You know were that gets ya when you need parts in a pinch.

My point is measure everything yourself and try to stay with the same product If you can. At least It will all Fit.

My only other choice is to have Gear one start making trailing arms. I doubt it

Thanks for the info..The car im buying is setup for Tatum 934 midboards and im wondering if I can switch them to Pro-Am's or Fortins without having to redo the trailing arms..

The Tatums were copied directly from Fortin, so the Fortin should fit.

Just make sure the u use the right bolts. For some reason, thats the only thing that everyone doesnt copy.........or patten......hhmmmm.

get out the trusty Caliper it will save you the headace.
Tatum likes to do it different and with them pissed from the mid board and centerboard dellema with gear one Ill bet there different.
