Finally some breathing room at work, 3 of 4 deadlines mastered, another one Tuesday.... Installed my second Mastercraft seat. Driver's side is a new Pro, a deep bucket w/ removable cushion; passenger side is the Prerun model I had on the driver's side at BB'03. The removable cushion of the Pro has been built a bit thinner at my request so I can sit a bit deeper, that way the headrest is high enough so as to NOT snap my neck in case I'd get rearended. Here are the pics: Driver's side mounts are 5/16 grade 8 hardware; I'd like to get it a bit higher above the rail (it's 5/8" now, would prefer 1 1/2"); I think I might be able to get a few pieces of solid aluminum to cut spacer blocks. Passenger side is the stock tilt mount (thanks to backyardbuilt for selling me a spare set!) modified so that it's 2" lower in the front, then a 1/4" stainless steel plate and then the seat, all mounted with 5/16 grade 8 hardware. The rear bracket with the hook is mounted with four 3/8 grade 8 bolts. I used grade 8 1/2" nuts as spacers; all four are fastened with grade 8 flange-type locking nuts. Right now everything is solid and tight, but I don't like the stacked spacers. Either I'll go aluminum like I have planned for the driver's side, or I'll have a shop tack-weld the nuts so at least they can't move relative to each other. Driver's seat position is nice, tight and comfy; seat belt length and position is probably o.k. I'll probably velcro/rubber strap the buckle so I don't sit on it every time I get in the truck, and then have to dig it out. I've driven the truck around a bit (actually only to the hardware store), and now I understand better what Stephen Watson meant when he told me he's always trying to feel what the truck is going to do in a given situation. With so much more contact area in the deep bucket, the feedback you get what's going on with the truck is much better without being harsh or uncushioned. Getting in and out of the truck is a bit more of an affair, but that's where the roll cage literally comes in handy - NO yanking up on the steering wheel, took me long enough to rebuild the column!! So far, one day, and I like it!
