air conditioning compressor

[Mike Arman <armanmik@n-jcenter.com>]

Changing A/C compressor on my 86 5ks - stock is type A-6, I can buy it for
$157 locally. There was talk recently about a ND conversion which works
better, is lighter; who knows part number and price for this? Any other
parts needed - brackets, hoses, misc bits?

Also replacing drier and converting to R-134 - mobile A/C repair shop doing
this, but he says I can supply my own parts.

Like to DO THIS this weekend, so if you know the answers, don't be shy!

TIA and Best Regards,
