'tool time' story: how I recreate my MK 4

[dkp_cobra]

My wheels are back. Here you can see the difference:
   

   

   
   and from behind:
   

   
   Since I have removed the transmission tunnel I build something for the security but I hope I will never use it:

After powder coating the parts look better:
   

   

   
   Now, if you think I have nothing to do since the car is finished that's not quite right. I still have the problem that I get a hard beat during change of load. That was the reason for the new transmission mounting bracket. But the problem is still not fixed.
   
   In the meantime I found three places where the exhaust could hit the frame. Now, I had a closer look to my new engine mounts. On the right side there is only 1 mm space between the frame and the engine mount. I guess that's a problem.
   

   
   And the next problem is that the ignition system is dead. There is no ignition spark at all. And this error happens when we started for a vintage rallye right on the start ramp [B)]
   
   So I think I have to replace this part:
   

   
   I ordered a new MSD AL6 box with new coil and a new distributor cap hoping that the problem will be solved with the new parts.
   
   At the end a look at a rear up MK IV:

Last time you could see how close the PU mounting brackets were placed at the frame. Here you can see these brackets beside the standard ones:
   

   

   
   Now, with the standard brackets I have much more space to the frame:
   

   
   Unfortunately, this doesn't solve the beat during change of load  :(
   
   But I have a new ignition system from MSD: a 6AL box. This is much bigger than the old Ford Duraspark box so I needed a new mounting plate:
   

   
   with a new place for the generator regulator:
   

   
   At the end everything had space at the same place (here, before routing the cables):
   

   
   With the new MSD box the engine starts fine, the tachometer works but the fuel switch-off relais which gets its trigger signal from coil(-) doesn't work. So I measured the signals from the tacho-output and from the magnetic trigger. Maybe one of them can be used.
   
   The tacho-output is a defined 12V square signal but the squares are 12V + and the trigger signal needs 12V -. The signal of the magnetic trigger are negativ but totally useless for the switch-off relais. The solution should be the tacho-adapter MSD-8920. I will check this in winter ...

I got the MSD Tach-Adapter 8920 and it works fine. But the first rides show that the speedometer doesn't work correct anymore. The reason is that this MSD box produces quite strong magnetic fields which disturb the hall sensor at the gear box.
   
   The solutions seems to be the separation of the ignition from the rest of the electric. This means that I have to modify again the cable harness.
   
   Now, below the battery only the ignition modules are placed:
   

   
   The external voltage regulator must be placed anywhere else. Since I expect that this will be the next component to fail I looked for a place where I can replace it easily whithout demount half of the harness:
   

   
   What is missing is the special cable plug:

Voltage Rgulator plugs are "dime a dozen" here. Two dollars or so.....I will send you one if you need it.

   That's very kind but I ordered it already.

I have a question: what do you think is a realistic price I could reach if I sell my MK IV? No, no it is not for sale but I would like to know your estimations.

   Why not... the more we know, both buyers and sellers, the better off we all are!

I would also like to know what a realistic price may be because I will have one for sale soon.
   
   Thanks,

   AKL1397?

[Brian]

yes. Trying to gather information.

Wintertime is time for some handicraft work. Starting from useless but nice to have things like a plate for a rallye plate
   

   
   going via some real improvements like a guide for the quite long steering column. Together with a new u-joint the steering is much more precise.
   

   

   
   Finally, there is real necessary work. Maybe, you remember my problem with a hard loud beat during chance of load. The reason was that all four bolts of the lower mounting brace of the differential case were loose. I think the problem were too light washers. Now, I have some real big washers with new bolts an a new wire lock.

What's new? I am currently working on a replacement of the bowden cable for the carburator. I would like to use some kind of rod linkage.
   
   




   I think this will be the last work on that car. After that a new project will start because, finally, grandpa has come home [:)]
