Hi thar. I have a 2000 Lincoln Town Car, and unsurprisingly the air shocks in the back blew out. I have some to replace them, and I know how to replace them, however the only thing I have to get the car off the ground is a regular hydraulic jack. Anyone have any thoughts on how I can keep this thing in the air without much risk of it falling and killing me? I thought about stacking some extra tires I have under the frame but not sure how well it would work. Any input would be appreciated.
