Thank you for all your answers.
Finallly I bought 2 things :
- The de Tomaso Pantera Ford Service Manual
- And a CD : Pantera 1971-74 Master Chassis & Body Parts Catalog CD.
What need to be done on my car :
- Accelerator cable to be change
- Upper engine gaskets shots, if anyone can tell me a little bit about what parts to buy and how to do it...
- Overheating, but since I have put new coolant liquid I should re-try to check.
I will probably open a new post about that.
