Sonic bolster ? Too Old???
 

Hey Fred or anyone else that may have removed some bolsters from a sonic...are they through bolted or screwed into a block? I want to replace my carpet and put snap-in in my 31 its glued down now....

I put a 4" access port (screw in) and installed stainless T-Nuts from under the floor. A lot more secure since the floor is foam cored with a thin layer of glass on both sides. I used stainless button head bolts thru the mountings. Easy to remove and doesn't mess up the hold threads.
