I did use a rope and ratchet to hold the dash out of the way whilst the matrix is removed. I dropped the blower motor out of its housing to gain a millimetre or two more clearance.

Old matrix out

Leak visible top right of the matrix in this pic. Explains why I had a leak from that corner but not from the seam in HSpw's thread :good:

New one in

New seals fitted even though the old ones were only a week or two old, since the new matrix came with spares. Surfaces cleaned and greased with red rubber grease as last time.
Took the opportunity to clean up the inside a bit and replace a load of trim.
