Mikes video is awesome but I Figured I would share my experience. Hope it's a help
Replaced the cracked crappy original bumper fillers today using spool fool productions 1 piece fiber glass filler I picked up at kirbans open house.
Huge thanks to Mike Barnard spool fool for answering my questions at the open house and on the phone.
Fit and finish are excellent, great product. Pretty easy install, just had to make some of the holes a little bigger. Lined up perfect.
phillips head screwdriver
7/16 socket or wrench
13 mm socket
possibly a round file
( tip from 626gn a 5 gallon bucket and a towel are the right height on a stock car if you don't have a helper )
sprayed the nuts with wd40 the night before
Had to make some of the holes a little bigger on the fillers and move the piece behind the plate a bit to get a good fit. Once it was right installed the nuts then I re installed the taillights
wrapped the edges of the bumper with masking tape to protect the new fillers gellcoat finish then put the bumper back on
