Cheap Longer Bumpstops

1.5" thick wood backing with 3" galvanized bolts. My
front stock stops are 2.5" thick - so total thickness is 4" now.
I did the same in the back. 5.5" was a little long, so I shortened the wood
backing to 2.5" thick. With the back stock stops being only 2" thick, this
makes for 4.5" total. I used 3.5" long galvanized bolts back there.
I gave them some pretty hard hit this weekend, and they seem to be holding up
well.
