Count me in as a happy customer...I did the seat lift on my 2005 S40 and it makes a big difference for my 6'1" frame.

Here's the details of what I did:

1.  I went to a marine supply store and bought 2' of neoprene strip that is 3/4" x 3/4" (cost $4.00).  I cut four pieces the same length as the rubber spacers on the seat bottom.  Using Gorilla Glue, I stacked two of the neoprene pieces on top of each of the rubber seat spacer that rest on the frame.  For the middle spacer (on the slope between the driver and passenger seat) I glued one strip of neoprene, which I subsequently cut down with a sheet rock knife to get the seat to sit properly.

2.  For the front bracket, I went to the auto parts store and they gave me scraps of hydraulic hose.  I inserted a piece of 1/2" hose into a 1" hose; it fit reasonably tightly.  After step 1 above, I measured the new height of the holdown bracket and cut the hydraulic hose to length.  Since the hose is black, it looks great and works fine because the 2-hose spacer assembly doesn't compress much in a longitudinal direction.

3.  I had to buy longer bolts for the holdown bracket.  I live in a small town, so I got the longest I could...they were about 2 1/2".  Cost $2.32.

4.  The rear holddown screw I left as-is.  So the overall effect is to raise the driver's seat by about 1 1/2" while keeping the passenger seat on the fender where it was.

5.  I didn't do anything with the two side holddown bolts for the seat...the bolt holes don't line up now that the seat is raised.  The seat installation appers to be fairly firm using the front and rear holddown, so I'm not worried that it will go anywhere.  I toyed with the idea of making a tang (a strip of metal with holes in each end) to span the gap between the mounting holes on the seat bracket and the mounting holes on the frame.  This would require new bolts and nuts on the frame side.

6.  Lessons learned?  I should have used superglue because I had to wait overnight for the Gorilla Glue to dry on the rubber pads.

7.  Any entrepreneurs out there could easily make a kit that included rubber seat pads, superglue, bolts, and hydraulic hose or stoppers.  Cost of materials less than $5, could probably sell it for more.
