Backdraft Valuation
The telltale for the brakes hose is if you have a solid rear rotor you use the early brake hoses.
The E36 rears are are two piece hoses in any case and a set from ECS are more $$ than Iconic's price.
I'd Call in the order to Iconic as shipping is a whole lot cheaper that route vs the website.
