where is the screw i undo to let the gas out? is it the bolt on the end? or somewhere else?? or should i just drill it??

 

 

Remove them from the car first, then clamp in a vise. Drill a small hole (1/8") if you can't find a screw.

Are you converting to 240 bumpers?

I Remember unscrewing that Philips screw on the front of the shock and it letting out a little bit of the gas. Tightened it back up due to me wanting to keep the pressure in. But that might be your best bet! Wear safety glasses as its pressurized. Just out of curiosity, why are you de pressurizing them?

Want to de pressurize to push them in a bit to get bumper closer to car.  Will that work?

I don’t want to drop tank unless I have to  to get right shock out. 

The tank has to come out to remove the inner nut attached to the stud. If you’re trying to remove the assembly that’s the only way that worked for me. 

Here's a couple threads with info on compressing the bumper shocks:

I am trying to find a way to get bumper closer to car without fully removing shocks. That’s why I’m thinking drill and compress them.  

 I drilled my early 260 shocks and they compressed back to the point where the bumper looks good. One shock wanted to re-extend out a bit after drilling so I installed a screw to hold it in place.

cool how hard is it to drill the hole and how close to car body do you need to drill the hole?  Does it explode when you get through???

It was many years ago. No explosion but one of them did squirt some oil. As I recall, I drilled them about half way which may explain one of them rebounding. Try drilling them closer to the rear of the cyl.
