ok i have a 1 car garage its a little narrow, i am getting ready to change clutch and i went to walmart and bought plastic 4 plastic ramps. my question is i intend to drive up on the front 2 and then jack up the rear and slide the other 2 ramps under the tires. does this sound about right? if so where do i jack from the rear so i can have both rear tires uo? should i do it on the rear axle housing? and the car can stay on the ramps for days right? im placing 2 horse under the subframe should the plastic ever give. ok thanks for any help in advance or if anyone has better ideas
