This took me about an hour and a half to make..all i had was a dremel tool. If i was going to make this for someone i could only make the cover itself and includ the bolts and hex nuts. The install would have to be done by the buyer. They would have to make small ones in the floormat. The holes to the floormats are not that big and wont be noticeable (just as long as you can squeez the bolt through) in the event that you would want to take off the covering. The blots were then set in place by hex nuts. The blots i bought were a little too long so as soon as i was done i just cut then shorter with the dremel..therefore my mats wouldnt look like i has a large lump in the covering area. If anyone in the bay area needs help on getting it done would i would be happy to help out. You can also change the color of the inside of the hole if you want..there is black vinly backing in the pic..but i can be easily be done with red, blue, yeloow..whatever. Ill try to do an install if i make another on for another celica owner in the bay..and well take pics. BTW thanks for the compliments.
