Hi Hemihunter, the company is called Titan. They have a division specialising in the manufacture of race grade components.

The contact that handled my rack creation was Mr Brian Love.
The rack ends require slight modification, in that they need to be threaded a further 50mm and then trimmed by 50mm. Titan did not have stock ends to suit the Pantera at the time. Any good machine shop can undertake this task with confidence. They have a standard 1/2" thread.
Kind regards,
Brendan Blake
