Shifter Cable rebuilding for man box.

[Jeff]

If anyone here works/knows/can suggest an engineering firm that can construct a new shifter cable.
For the full story check out the last page of Danny & Jeff`s 6A13 turbo conversion under the performance section.
I need 2 push / pull cables made that will withstand a lot of heat that can be adapted to go from the gearstick to the gearbox.
My turbo has twice melted the inner plastic sleeve of the original parts.
If anyone can help please post. I can send the part to an engineering firm if they think they can do the job.
Thanks in advance.
Jeff
