Banzai diff brace + PPF adjustment
Hi guys,
I tried to install my new banzai racing diff brace today. The holes on the chassis don't line up on the driver side. I tried to jack the diff, push/move the PPF, can't line up the brace with the chassis holes.
On banzai racing instructions it says that the PPF needs adjustment if the holes on the chassis do not line up. I looked in the FSM to know how to do it but I don't understand how you can adjust the PPF. I mean you can only fit the hole of the PPF in the studs of the diff, right?
BTW I'm pretty sure that my diff bushings are in good shape.
Thanks

The PPF is adjustable at the trans end, just like it says in step 7 of our instructions where it provides you with the page number for the FSM.

If you are supporting the car on the chassis rails it will pull the body apart, the car needs to be supported on the subframe for proper installation.

Even after reading the FSM (p. J-59) I still don't understand what am I suppose to adjust. It's not clear. What the "caution" of the step 7 of the FSM means: "If the distance is not within the acceptable range, readjust the PPF." How do I readjust it? Do I have to rotate the diff? Shim the front of the PPF?
On a side note it would be great if you could mention the following in the instructions, I'm sure it could help many of your customers, because:

Pretty simple. The PPF holes on the trans end are slotted. Loosen the 4 nuts, install the diff brace and retighten. The PPF will automatically be aligned correctly with our brace installed.
Step 7
If the side-arms of the brace do not meet the body mounting locations on the chassis, then your PPF is out of adjustment, your differential bushings need replacing, or both. Please click here for directions and inspection tips, or refer to page J-59 of the Factory Service Manual. You will need to loosen the nuts at the transmission end of the PPF to make the necessary adjustment.

Back up from the dead! Gotta love searching!
Anyway, I am having a hell of a time getting the Banzai differential brace to fit on my car. The rear sub frame and differential bushings were all replaced with solid Delrin replacements. I have been trying to align PPF to get the last bolt to go in and it will not line up.

Here is a picture of the bolt I cant get to line up. Also the side body mounts are about a 1/2' from touching the body. Any advise would be great!

That is not a bolt, it is a stud, put it in the diff then follow the instructions.
If the diff brace arms are too far from the body to start the bolts, then you have the tail shaft of the trans too low, loosen the bolts and raise it up.

Thank you Banzai for your fast response.
I knew that was a stud and not a bolt, I pulled it out because I could not get the brace to line up and wanted to see how far off it was. I will try to use a just to lift the tail shaft of the trans up and see if that helps. I want to avoid grinding out the holes to get this to fit.

Banzai,
I have messed with this brace for over 4 hours and cant get it even close to fitting. I have attached photos showing how far off it is when mounted to the body compared the Diff. I also took a photos showing that the PPF was adjusted at the rear of the trans also with no luck. I will PM you about a return/refund.

It fits fine, it can just be difficult for a diy guy without a lift. There is a lot of adjustment in the ppf. I usually loosen all the ppf hardware, then place a screw jack under the trans and another one under the diff, then manipulate them until everything lines up. You may need an extra hand and and a big prybar between the diff and subframe but I've never had one that I couldn't get to fit. If it doesn't fit most likely your chassis is bent.
