Vacuum tank weight?

[Twin_Turbo]

The pace car seats are much much lighter than the earlier seats. They are mostly jut the plstic shells and the light hinges on the sides.

One substantial weight savings is to dump your 69 seats in favor of a set from a 81 or 82, they are a very simple swap using your seat tracks and the foot of the 81-82 track, these fit very nicely, better access into the rear area and weigh less than 1/2 as much as the 69 seats, I did this on my 70 and have photo sequence to show what to do.

I've got a line on some late C3 seats, but don't have any weight measurements on them yet. I'd be interested in your photos. How about starting a new thread about them, along with some details?

thanks

Mike I've been meaning to weight a 79 style seat (pace car) for you and finally got around to doing it today. Complete seat with cushions , carpet on back and tracks weighed 25.5 lbs.

Thanks for the info, Roger. I appreciate it.
I'll probably pull the passenger seat out of the car this winter and put it on the scale for comparison.

Just weighed a seat w/ track from my 73. On my bathroom scale it came in at 41 lb.s

I appeciate it! You just saved me some time and work R&R my seat to check the weight. Looks like a ballpark reduction of about thirty pounds (total) with the newer seats.

Just what I was thinking

wonder why aluminum cast HB units not out there???

Gene,
I was thinking the same. A friend Tony has a '73 with a 600 hp rat and a Hydraboost. He let me have a drive a week ago and it's a ripper. The brakes worked so well, I forgot at the time that it had a HB. But afterwards, I thought why hasn't someone made a cast or even billet HB housing? Can't be too hard as it's not that big a unit. Not like a diff centre. Add an aluminum MC and there's a few kg gone. Alternatively, why not use a later model C4 onwards plastic vac. booster and aluminum MC?

I'm looking at using an aluminum MC with an inbuilt prop valve as fitted to late model Holden Commodores and even Ford Falcons. They're made here and are not expensive. That would get rid of the prop valve (???) on the frame under the MC and tidy that area up somewhat. It would also lessen the number of brake lines, fittings and therefore potential leak areas. I'm all for replacing two separate units with one "combined" unit if it's both aesthetically pleasing and functional, as well as cheap.

That's why I'm also going to fit a Borgeson integral steering box in the near future. One of these days, it will be finished and I can get it registered and take it for a drive...............Hmmmmmmmmmmmmmmm.

Because no one in his diesel dump truck could give a rats ass if the thing weighs a ton.

Hydroboost seems the wrong way to go if you're trying to reduce the vehicle weight.[/QUOTE]

Use a aluminum M/cyl to make up for it....the superior stopping is well worth it...

I already have an aluminum m/c (C5 @ less than a pound weight), and the HB stopping superiority claim is ********.[/QUOTE]


Well, I mis spoke, not stopping, superior pedal feel and travel charactoristics, that by just superior driveability, make it feel better on the brakes end of things.....

and TT, you right...another 20 lbs on a 8000 lbs truck don't matter a damn....
