I know you also commented on my post, but you didn't post this picture there. I don't use that spacer, just put a paper gasket between the booster and the firewall and you're good to go!

Thank you so much - appreciate it!

Few questions - just want to make sure i did it right. @Meap @McGarryR32

The “U” the clevis pin goes through is shorter on the 35 but can be swapped over for your original one as they’re the same thread.  (regarding this) do you notice your brake pedal sitting a bit lower than the stock height? i had to adjust the switch lower so that its touching. i have adjusted the bolt to the end of the U but the pedal is a bit lower - is it the same for you guys as well?

does anyone know the specs of the R35 master cylinder, rear ratio and knee point?

the BM57 is a 0.4 rear ratio with a 435psi knee. I'm looking for someone with a much lower knee pressure. the piston area of the R35 brakes isnt that big so might not work for me but this is interesting..

the other option for me is a GU patrol master cylinder and booster and do the prop valve externally.

      I am currently going this route. I am curious how much horse power you put behind the cut bell housing? Collins was telling me I am going to crack it and bluh bluh bluh. Because I didn’t buy the custom fly wheel from him. I am looking for somewhere around like 500 hp

      Thanks @PranK for the updated member status, much appreciated! 👍🏼 Now, about those pics… Unfortunately I could only find ones that I took in the dark. I was soon to discover that underneath it wasn’t in the best shape, but it was mine and that’s all I cared about at the time 😆

      A little PU bush story

      By GTSBoy · Posted

      Oh, and only having done this task yesterday, I've now driven the car ~60km since, and while it is hard to avoid placebo effect and confirmation bias, I reckon that some annoyances I had with the way the car has been behaving have improved. Which....kinda makes sense, I guess. If the bushes were really stiff and resisting rotation, they would have been contributing to the effective wheel rate. And if it was more so on one side (which it was, because one side was worse than the other) then.... you might imagine that the additional rate would be asymmetric, and potentially even different between compression and rebound. And so... the car has been twitchy at higher speeds - like freeway on ramps. It really shouldn't be. The wheel alignment is good and there are no (other) known problems elsewhere in the suspension. But at 90-100 on a long sweeping ramp, tiny steering wheel motions would make it feel like it wanted to rear steer. Quite nervous. At lower speeds it would heave about in a manner that it didn't use to. Didn't want to put power down, etc etc. Now...seems to behave better. Am going to have to concentrate on the various corners where it has exhibited weirdness, on the rare occasions when I can get a decent run at them without Methanial getting in the way in his D-Max/Ranger/LDV Van/etc.
