MX light leaks - help please


I recently acquired a used MX which is in good condition on the whole, but had virtually no light seals or mirror bumper left. I took it in to a local shop for a new bumper & seals (34) and they now look ok to me except inside the mirror box, along the sides of the focusing screen. Here they do not seem to have been replaced but are not severely degraded. I can't imagine much light getting in there.

I've now run a roll of film through the camera & quite a few of the shots show light leakage. Most of the shots are ok though, so it's intermittent. Some shots were entirely destroyed.

Ths most common leak seems to be across the centre (top to bottom), and I thought maybe the judas window is causing it?

Any suggestions would be much appreciated.

have a look at the negs... if the over exposure goes outside the image area (i.e across the edges/rebate) then it's most likely the rear door.
