As far as diff or gearbox (Or both)?

Paul.

Paul's insane prices are on the attack again. Just a heads up to anyone who thinks this is too good to be true..It's not. I've been dealing with Paul and Mazmart for a bit and their service is simply top notch. Any questions and I'm 210% sure that Paul will gladly take the time to explain what is going on so you know whats happening.

I'm usually a bargain hunter (thanks to my Mom..ugh..) but honestly, This is one of those "regardless of price" kinda places. You just..It's hard to find this kind of commitment and service. :suspect:

That would be both.

As far as the ratios, there's a lot of figuring you will need to do in relation to your exact application which for some differs from race to race. Our experience with a top Koni Challenge team we deal with suggests that the new gearbox is holding up much better than the Aisin units they used before.

Paul.

you will need the spacer plate to install the 09?
OD

per ASH's posts from the tech section yes you'll just need the spacer plate

There is apparently a spacer now, correct. I will provide these for 0 dollars to those getting gearboxes from me.

I have Paypaled you the payment for the 4.777 rear end gear from the 09s but it seems that you haven't accepted it yet. Is there any problem?
