I have to thank "Spooled-up" for the great idea for fixing the uncomfortable front seats. However, I made a modification to his design that worked very well, for me. Instead of the thick, regular foam padding, an upholstery store mgr. recommended going with a 3/4" closed-cell foam material. It's a much more dense material & doesn't seem to collapse nearly as much as the thicker open cell type of foam. It, also, doesn't create a large 'bulge' in the center of the seat like the thicker foam does. This WAS the answer, for me, & it worked great.
I have a friend who has spent his entire life in the automotive design business & is the fussiest guy I know, by far. I explained what I did, to him, & he was impressed with the results.
I don't mean for this post to be critical of what Spooled-up created. It was HIS idea, in the first place. I would have never thought of it. I, even, approached a couple of automotive upholstery shops, in the area, & they wanted hundreds of dollars to fix the problem. I did it for less than $10. 00 & have enough material to do another set of seats.
This is not the end of "Spooled-up's" genius. I did his Fuel Tank Vent Kit Mod & my results were terriffic. I HIGHLY recommend this modification if you like to fill your tank right to the top. IT WORKS!!!!!
