Is your Z an early Series 1 or transition Z? I had the same problem with my 70 Z. Seems the attachment points on the later model cars are farther back. My solution was I rotated the mount 180 degrees. Can't remember whether I had to drill another hole for the bump stop or not (don't think I did)..The notch for the brake lines will be on the wrong side, but there was no contact with the lines anyway. My Series 2 cars worked fine.....just the early cars.

Sorry, I should have noted my 2/71 production date which I thought was officially the beginning of series 2. I am not aware of a "transition Z" so I'll need to dig in on that. I am on a tablet so I will post a better reply tomorrow.

Yeah we all know what it's like be bullied by the all knowing.

When I read the hybridz info I saw that Zed Head had some expirence with the rt mount so I "tagged" him for you. We're all friends here and happy to help.

Yes, I already like the atmosphere here ... fun, friendly, and informative. I already get enough buzz-kill in the non-Z world that I don't go looking for any extra.

Yes, that's why you're having a problem. The early Z's had a different mounting point for the arrestor belt mount which put the bump stop bolt in an interference point with the e brake mechanics when you install the RT mount / TV mount. Yours is a transition Z (half Series 1 and half Series II). Try the mods mentioned above.....it'll solve your problem.

I have installed a few of these. A couple of the tech versions on a '73 and a '71. And a RT mount made by roost monkey on my '73. The RT by roostmonkey bolted right in. The ones made by tech, I had to widen one of the bolt holes enough to get it to bolt in.

The RT mount by RM, didn't have the bend for the brake lines. It cleared fine just the way it was.
