It was a post to give an example. You can always call Wilwood and see if they will offer the HB unit alone if you want a different master cylinder. I'm still unclear on exactly WHAT it is you're looking for. Individual components to build your own? Trying to keep price down? 450 for that entire unit is pretty reasonable given comparables available, so I am not understanding what you're after. Seems to me it's a totally bolt in unit. Was that not what you were looking for?
