Daryl - thanks for the memory jog, you forced me to go back to my notes . you are right , it is a BTR ( not BDR ) rear end - my goof .

my notes from late March 2005 from SPF -USA HQ ( in Virginia then ) said :

They were switching the roadster MK III rear ends from a Ford unit to a BTR unit . This was to occur at about SPF chassis number 2068 .

BTR was a susidiary of Dana in Australia - and BTR was also the supplier of the Coupe rear end . although limited slip might be different , hydraulic on the coupe and cone on the MK III . at that time someone told me the BTR part number was " 0180-000007".

supposedly several rear ratios were available with the BTR unit , but 3.46 was what SPF was going to use then as their standard ratio .

now, why I hard copied and kept that email note is beyond me ...

as an aside, it was about the same serial numbered chassis where SPF also stopped using the center rod on the windshield . trivia for ya ...now, when they started using the center rod , can't help ya there . my old 156 does not have one . Bill.
