I'm installing new brake lines on my 88 Gta and the sites say with hd rear or non hd rear. I have the 9 bolt and the lines for the non hd rear look like mine with the 180 degree turn on the driver side. I though the 9 bolt would be the hd rear but the lines pictured don't look like they would work. I received new ones from SS brakes and the passenger side where it comes over the axle doesn't fit into the distr. block on the axle. The 90 isn't short enough. I'm trying some from Right Stuff and I ordered non hd again going by the picture. Am I right in thinking the 9 bolt is the hd axle or Non hd axle?

 

Going to venture that the HD they're referring to are the HD brakes (ie 1LE, more accurately PBR calipers). The books and computers have forever been plagued by the presence of a brake system that doesn't apply to 99% of the people buying brake parts. If it asks anything about HD anything in regards to brakes, it's almost always talking about 1LE brakes.

 

Ok thanks, I was thinking it referred to the 9 bolt being a bigger rear end.
