Lowering the seat rails
I tried this on the technical board with no luck; therefore, I will try it here...
I have an 83 SC CAB and I am replacing the interior--including the seats. I have a pair of 2-way power from an 86. all is good except that I sit a little too high (as in staring into the visor). I want to lower the seat rails (about an 1") and actually move them back about an 1" but I can not find anyone to perform this for me. some have declined due to the fuel lines running through the center tunnel...etc. I am open to suggestions or if anyone knows someone one in So Cal (LA and south) who would perform this task, I would appreciate it. Brad

the fuel line does not run all the close to the seat mounting brackets . but run the car (drive it) untill most of the fuel is gone drain the rest . remove the seat brackets and reweld them were you want them .

Problem is that I do not have welding experience which is why I need someone to do it.

Fuel lines are clipped very close to the driver's side inside tunnel....and they are made of plastic. So...the danger is there because 1.) yes...it *is* that close and 2.) it's plastic and can't take welding heat . How can people say it's not a problem?........

When I did this in my race car, the fuel lines did melt. We cut the seat rails off and welded a support brace that runs between the sill and tunnel. I'm not sure we could have avoided it the way we went about it. Depending on where you weld you might be able to avoid it. I would think someone like TRE Motorsports would be a good option to do the work.

Those plastic fuel lines are likely to get damaged if you try and weld to the tunnel. This thread shows an interesting alternative that looks promising:
No weld to tunnel seat lowering |

amjf088.... great post... I was trying to find that post about using nutserts.... good find.
Pictures are always good----> Need help with fuel line install - '88 ...........and read the text that you are viewing a tunnel that is cut out and is place upside down on the ground....so the labels are mirror-image opposite when viewed in the upright, installed condition, as someone on that thread mentioned. Fuel lines run, IIRC, in the drviers conduit, awfully close to the driver's side vertical wall of the tunnel...and clipped too, IIRC.

remember that any solution that you come up with needs to withstand significant force in an accident. In the non-weld method, those appear to be pretty small bolts into 18 gauge sheet metal. No thanks.

wil wanted to know how can any one say its not a problem ?....... you don't mig of tig weld it !!!!!!......... and if you realy think your going to burn some thing you remove it or shield it from the heat . this maybe new to some resistance weld it ??? resistance welding can be done from top side and bottom side or top side only keeping the welding tips 3 inches or more apart . it has very little heat on the back side of a panel and the heat is concentrated to a spot about 1/8" size things like plastics will not get burned .
