If you live in an area that uses chloride salt on the roadways during winter months chances are you will break a seat bolt or two when trying to remove the front seat assemblies in your panther platform vehicle.
This article describes one method of dealing with the extraction and replacement of the broken bolts and replacing with suitable hardware.

How to replace broken seat bolts.
First you will need a few tools.
- BFH aka 8lb sledge
- Drill w/assorted bits
- Punch(Something you can hold and hit if the bolt is snapped off to far down)
- Grade 8 and above hardware(unless you like the idea of having the seat snap off in a wreck)
First remove the seats and the carpet at least far enough to access the bolts.
Now the simplicity of this method takes hold.
BASH the exposed bolt with the BFH. Drill a notch for the punch to hit if you need to use one. 3/4 bolts are held on only 3 spot welds.
once you get it knocked loose you will end up with this.
Now if you get unlucky like I did you will break the Beefy bolt on the rear inside corner of both seats.
I applied the same method with some success but it took longer. The regular bolts came out in 5 min. The beefy sucker to about a hour of pound before the crash bracket gave way. After I got the bracket removed to were I could work on it I drilled out the welds. (so no pics of the crash bracket drilling was in a rush)
Ended up with this after a little paint.
I then drilled out a few of the spot welds so I could insert tapping screws with less effort.
Notice all the holes in the floor form the weld being stronger then the metal.
I bolted up the main seat bolt to hold it will i inserted 3 tapping screws.
I then proceeded to fill all the holes with some silicone.
After your done letting it dry put the carpet back in then bolt up your seats. You will probably want a assistant for this part. I preferred positioning the bolts upwards so if I have to do this again they hardware hasn't been hanging exposed and having to start all over again.
I recommend using grade 8 Bolts or above. YOU DO NOT WANT these snapping on you in a wreck.
I spent $13 on three 19mm x ~2" long 8.8 metric bolts and nuts and a handful of washers to spread out the pressure.
On the crash bracket bolt I used 2 washers on top and 2 on bottom. The other 2 bolts received 1 washer for each side.
