For all of those with the utility rail system on thier Tacoma's I have found a easy way to hold down your jacks without putting a hole in the bed... What you will need is two 1/2 in X 3 1/2 in bolts, 4 washers, and 6 nuts. The bolt heads will slide into the utility rail system on your truck and give the jack something to attach to... Use one washer and a nut per bolt to hold it in place on the rail system then place one more nut on each of the bolts screwing it down to about 8 threads from the other nut. Set your jack on the bolts, slide the last washers on then simply secure the jack to the rail system. All in all the parts should cost about $4.50 from any hardware store which beats the hell out of the expensive mounts you get elsewhere! IF you do this right the jack base will be about a 1/4 of a in from the rail system and not vibrate at all.... IF you need pictures let me know and I will send a few... Happy WHEELIN!!!
