[DeTomaso] Pantera AmeriSport GT5S 1987 Parts Info Request - Montana 5/18/20

[Julian Kift]

Strictly speaking it is the VIN as US DoT required 17 digit VIN numbers by this time and this is what would be on the title. The De Tomaso last 4 digit serial # of this car I believe is 9459.

That’s not the car’s VIN, is it an Amerisport serial #?

Mike Drew sent me the following info and has been a great source of info as usual.
As for the master cylinder, the question is not easily answered. The later cars like yours used a Bonaldi master that was externally identical to that of the early cars but with a larger-diameter bore. Thus the standard replacement Pantera master cylinder will not work.

The early master was 23mm and the GT5 series use 25mm bores.
I THINK but don’t know for sure that the one you need is shared with the later Ferrari Testarossa (512TR)
Looking around at Ferrari parts sources it seems the Testarossa uses a 1-inch master which is right at 25mm. I see them listed for sale here in England:

You could probably find a Testarossa master cylinder here easily enough. Here is one on eBay:
