Listen to the moderator ! There are about 170 Bar inside the struts ! I don't know of any small valves which withstand this pressure. Don't do it ! Elvis 6548 ( Moderators note: I'm sure this will generate several follow ups but in the interim: DON"T even think about it. Your dealing with very high pressure, even with old struts. ) A little while ago I read about some special door struts available elsewhere that are adjustable. I know how to get them, but my question is could these be made using an old pair of stock struts? Would it be possible to drill a small hole and pump them up (with some sort of check valve type fitting)? Thanks, Tyler #3472
