Hi Richard
I need to replace my heater matrix; according to the parts manual the part number is STC770; your website and a few others says that its been superceded by STC250, so I bought STC250 from my local supplier.
After a right game getting it into the heater assembly I put the whole unit in the Rangie, but the pipes from the heater don't match up with the holes in the bulkhead; they need to be about another 1.5cm apart for it to go through.
What's the difference between STC770 and STC250? One parts website I've seen ships them both (at different prices) and others say use STC250.. are they different or do i have one thats been made by a drunk??
