humm Zip ties are life savers.. I took my car to get an oil change.. and those basters lost screws. and they used wires to keep it in place.. humm when did my oil change, I came across that problem... I didn't know what to use to keep that cover in place, no screw would fit in that sucker, so my girl gave me zip ties.. and hehe no problems here.. Just of that, I never take my car to have an oil change.. I do it my self now!
Oh yeah, use Zip Ties!!
