Garage door failure and capping the heater channels

I went out to the garage the other night - as you do, I thought I'd have a tinker around for a while and see what's what.
After a short while I needed a piss so I thought "I'll just nip out the back, it's easier than going back to the house".
I lifted the garage door and one of the lifting cables came off the roller jobby and wrapped itself around the mechanism.....that was it - boned!
There it was, stuck fast, half up half down and no chance of getting it closed.
BASTARD!
It's been acting up for years.
I spent about half an hour wrestling with the thing before shouting Tom for help.
In the end we removed the cables and managed to get it closed.
It weighed a feckin' ton and dropped like a stone I can tell you!
I managed to get some spares off ebay, and thought we could fix the twatting thing Saturday

Man-John, Matt, Tom and me fitted the spares for the door today - I couldn't have done it alone, Bob Hope!
It's way better now, should've done it years ago........

With the time we had left we capped off the heater channels.

Both ends capped and ready for dressing

After Matt had dressed the welds back....Nice.
A bit of seam sealer, a lick of paint and you'd never know it's been repaired.Sweet!

It didn't seem worth starting anything serious so we lifted the bodyshell, carted it outside and turned it round ready for work on the driver's side door post.

Door post and associated front inner wing repair next time.
