-I am helping my son restore his Uncles 1975 Firebird Formula 400.

-Stupid me threw out the rear sway bar because the links looked so pathetic.

-I bought the PTFB rear sway bar. It seems all the products I have purchased from PTFB have no installation instructions nor pictures on their web site, very frustrating to me as I am not a born & raised Pontaic person so I am learning alot.

-So I spoke to Dave yesterday in regards to the install, but I am very visually dependent.

-So I attempted to install the bar and when I tightened that bar to the bushing plates that are under the axle one of the allen bolts was pulling through.

-I am just lost without instructions/pictures.

-Any assist is greatly aprpeciated

I don't have experience in this area or with the product,  but I would expect a washer inbetween the head of the allen bolt and the rubber grommet it is pulling through.  I would guess the washers hole to be just bigger than the bolts threads and the outside diameter to be near the diameter of the grommet.  It's hard to tell from the pictures, but it doesn't look like there is a washer there.

Thank you. Yes there is no washer there and the guy at PTFB stated he setup the configuration how it is to be mounted. I just don't know, gonna try to call him today.

Just got off the phone with Dave at PTFB. He stated that it is normal for the allen bolts to suck in close to the bushings. I will adjust the bar to even out the spacing. Thanks, GV

Ya, Dave's not big on instructions. You're not alone in your struggles and I've written "how to" threads on some of his products. I'm sponsored by PTFB and have installed most of his products on customer cars as well as my own. Great products for the price, but lacking in instructions. Drivers side bracket appears to be on backward in the pic to me Although hard to see because fuzzy pic.  The side where the collar is welded flush with the plate should be toward the inside.

 

Still looks kinda funny with so much of the sleeves showing. Bar should be about 38" wide, outside to outside where it bolts to the brackets. Check yours.

 

The allen bolt head should hit the outside end of the sleeve without getting pulled into the rubber bushing IIRC.
