Cheers Paul, i'm willing to try most things with this car now, knowing that if it goes wrong then i can re-do it!
So my heater has been stripped, cleaned, painted, reassembled and fitted
I've now plumbed it in and done a test drive to make sure it's all water tight.
Although i don't have a flow control valve in place yet, so atm it's hot-or-not.
Now it's onto the centre console ready for the incockpit piping, controls and electrics to be finished off and tbh i'm happy with how this is going, but it needs a bit more tidying yet.
BTW i've put these on photobucket, but i'm aware of the faff, so if anyone can advise of an alternative photo host that we're all going for then it would be greatly appreciated!
