Vette(s): 1969 Corvette Stingray Convertible. Just bought it from my uncle who owned it since 1971. Fathom green, green interior. 350/300, T400.

I was taking the body mount bolt out that is behind the rear wheel well. It just spins. I remember a thread quite a while back regarding how to fix this, any ideas?

Thanks,

Matt

two things..

the first is much easier and will save you time..

cut it out with a recip saw.. its likely the bolt is rusted to hell anyway..

the second..  you can try to dig broken metal cage out of the hole on the backside witha  magnet and then use a large 12pt socket to hold the square nut still while you loosen the bolt..

believe me.. dont waste your time on number 2..  cut the bolt..  buy a new one

Yup, just cut the booger! I cut both of mine in just a few minutes.

When you say the "backside", where do I get at it? As I'm writing this I'm at work so I can't look at the car.

Thanks,

Matt

Vette(s): 1971 T-top. I just had car shipped from my parents house in florida where it has sat for over 12 years..It is going to be a long project!
I agree with both of the above.  I tried to get to bolt head.  I have a 71 coupe and its about imposible to reach...its in the very back corner behind where your window storage tray and seat belts are.  I cut mine with a dremel.  Im not sure yet how I am going to put new one in but I'll worry about that in a few years!


Someday!

Just behind the rear wheel is where you will see the mounting bracket. You'll need a fairly small cutting head to avoid damage to the bracket. Cut the head off from underneath  and fish the old bolt out from the top, then thoroughly clean out the pocket.

To replace, I used a new body mount bolt from the kit but on the inside I used a big, thick washer, a lock washer and a square nut from the local hardware.

Mine just broke off when I tried to loosen them. Pull the carpete back behind the wheel well and you will "feel" an indentation where the nut is held in place with a small metal cage. The cage is held in place with 2 aluminum rivets. The cage usually breaks loose and the nut just spins with the bolt. Cut them off and replace them. Replace the metal bracket between the body mount and the body while your at it. They usually are rusted out anyway.
