The 003 trans Vac Mod is now in the hens teeth category Mine is running one from an auto 411! I know that that the Borg Warner box was in loads of cars in the 70s , loads of googling have not resulted in any info that could lead to another manufacturers code for the box or the modulator. There are loads of new cheap adjustable vac mods for sale one must fit. I need to find an ancient mechanic who can remember what they were in. Im thinking if a sort of compatible adjustable one could be identified I could make an adapter. . .
Can you not find an old-school auto-trans repair place? They could maybe find the part. The Borg Warners were fitted to loads of 70s vehicles. Might be worth having a look in Practical Classics for a supplier.
As below but without the c suffix, although it might fit. They are on Thesamba at times but they won't ship to the UK, some places have them on the stock list but don't have them. 003 325 391
