Some guys will say it's easy. others will say it's hard. I guess it's an individual thing. I thought it was hard, but not impossible, and got it done on the first try. I bought a nos seat cover & the material was stretchy which was helpful.
Basically, pry open the prongs to about 45
o & remove the old cover. pick off the debris from the foam & sand it if necessary. the foam was split at the center & it had separated from the pan at the front, so I glued those spots using 3M super 77 adhesive spray. let the glue dry overnight.
To attach the cover, I started at the center to make sure the alignment was right & did a test fit first. then sprayed the top of the rear section of foam w super 77 & started fitting the cover over the prongs. after I got the rear fitted, next I sprayed the front section w adhesive & did that part.
The material was stretchy, so it was hard to poke the prongs thru, so I used an awl to make a hole. In short, make mark with prong, poke hole with awl, press prong thru hole, use blunt tool to push material over prong. the instructions said to spray only the top of the seat foam with adhesive (
don't spray the sides). All in all I thought it came out pretty good, especially for a first try.
