Thank you guys for the true LR spirit shown by everyone.
In fact, I have two defender 90s. One is TD5 and the 2nd is V8 NAS. I have contacted RedDot when I bought my TD5 and requested the R-2000. The dealer here in Dubai suggsted that I install a floor-mount unit which I did (photos attached). It sits nicely in place of the middle front seat facing backwards. I found it a space-waster. Hence, this thread for the purpose of fitting the V8.
I am very interested in the South African fitments as Brian described. The problem is that air con specialists here are not so savvy. They are trained on a specific product and they just install and maintain that product line ONLY! No creativity ... just easy money.
I have a SA friend at work who can source them from SA during one of his trips back home.
If this doesn't work, I will follow Brian suggestion of doing it on my own.
