Imported mine from England a great quality product but a little costly.
 
 

from 'demister man' ? i too bought this same core from him, and as mentioned luckily adapted it to get it working, and it sure works great, provides good heat.

From memory the earlier mk2's (late 75 - 76) had the steel type heater box and the 77 on the plastic type..... Good to here you got it all back together and the 'adapt and overcome' spirit is still alive and well
Cheers Drew.....

yes, completely correct. wish i had of known this for a more 'complete' finish on the project. The steel box also incorporates the Mk1 heater core, quite different from the usual mk2.. never mind, it's in and working. just for reference, this is the correct heater core for the early mk2s
 

My RS is a 1980 model, with plastic heater box as posted earlier in this subject, Has the core with straight pipes which fits straight thru holes in the firewall.
