Brake Pressure Reg Substitution

[Don Muirhead <dmr@kwic.com>]

Having a bad Audi week...

An early morning panic stop to avoid a couple deer on Sunday has resulted in one toasted Brake Pressure Regulator.
  
'86 CGT BPR PN# 443-614-151-H  ($551.00 CDN)

'84 CGT BPR PN# 811-614-151 ($121.00 CDN)

I realize the '84 is drum and the '86 is drum/disc but I'm looking for Audi or even VW options on this rather costly item.  

I've had a couple of bad experiences with used regulators over the years, so that option doesn't don't tickle my fancy.

Any BTDT on substitutions?
