Stuff Needed:
One pair of Mk1 golf seats - the 3 point mounting type
One pair of old beetle seats or undamaged seat frames - 3 point mountings
Tape measure
Grinder with cutting disc
Welder and appropriate safety equipment
Bricks or blocks of wood
Cross-head screwdriver
Time taken: Half a day/ over the weekend
This How To is based on a 1972 bug with the three point mountings - the one with the hump in the middle of the floor.
What you need to measure is:
the distance the leg needs to bend in (length 1 on the diagram below) the extra height needed (length 2 below)
After you have rechecked your measurements, mark where you are going to cut on the seat bases.
4. Cutting & Trial Fitting
Now you need to cut the bases using either an angle grinder or a hacksaw.
When cutting, do not cut along the line, instead cut below so that you have some extra spare
Remember it is easier to cut off the excess than it is to fix the problem if you cut too much off.
Next, what you want to do is slide the front runner of the golf seat base into the front runner on the beetle.
Look at this from the side. Use bricks or some wood to make the seat base sit at the correct angle and make sure it is horizontal at the back.
At this stage it might be easier to fit the lower seat padding by placing it on top to give a better idea of height etc.
Now, take the two seat stalks that you cut off the beetle seats and place them in to the appropriate seat runners.
Push them up until they are against the seat and you can see how much more you have to cut off. Mark them up and cut this off.
5. Welding up and testing
After you have cut them, put them back in the runners and push them up until they meet the seat base. When they are in place, tack weld them in place with a few welds per stalk.
Don't
fully weld these in yet - you might need to change it.
TESTING
Now refit the seat base cushion and the back rest of the seat. Check that the seat moves freely back and forward in the runners. Check also that the height is ok for sitting on. If all is ok, take off the cushion bits and seam weld the stalks on to the golf seat bases.
Make sure you get good penetration of the welds by looking up the hollow stalks. When that is completed, grind down the welds so that the job looks neat and professional.
Refitting
As they all say, refitting is the reverse of removal. Seriously though, there are no difficult bits to the refitting process.
Before you start the refitting, paint the entire seat sub-frame with a spray paint.
Once reassembled, cruise in comfort.
