i was changing my front sping on the drivers side when i ran into a problem. i cant get the new spring in. i went to pep boys and rented a spring compressor. its the kind that goes up the center of the spring. no matter how i tighten it, i cant compress it enough to get in there. i had it in almost once but the threaded shaft is so long it hits at the spot where the spring meets the body. what do i do?
