Hey all,
was discussing twin diaphram boosters for a v8 swap,
so was thinking would make a good article with photos,
easy to identify the various Torana models and different types in each model,

What I want to know,
what does a 2 diaphram LX booster look like,
compared to a UC SLE booster?

Thanks
Chris.

LH and early LX double (straight rear pushrod to pedal)

LX and UC double (bent rear pushrod to pedal)

Posted Image

Both these units take the all cast master cylinder

Late UC single (bent rear pushrod to pedal)

Posted Image

This one took the plastic bottle Commodore master cylinder (15/16") with the diagonal mount

The only car to get the double booster (bent rear pushrod to pedal) using the diagonal master cylinder (1") was the A9X

Any Chance you could post the dimensions on the boosters in the pics? Diameter and length would be great.

ive been given a booster it has vh387 stamped on it near the seam. Not exactly sure what car it has come from. Looks to be a DD Booster. Can anyone confirm if thats the right one. of say a VN. I believe its off a commodore because the master cylinder with it has the oval filler cap. And the 1 stamped on it i take means 1 inch bore?

Any help much appreciated.
