Hydroboost 10-1740 Master cylinder question..

[Dynalow00]

I am slowly getting my Hydroboost installed. Looking at the 10-1740 master cylinder, it looks like you do NOT switch the brake lines like with the 84/85 master cylinder. I have not attached the metal brake lines yet, I am currently bleeding the master. Can anyone using the 10-1740 tell me if you had to bend the metal brake lines to fit, or do they fit like stock? Thanks guys!!

The lines will only fit one way. They are different sizes.

That's what I have found.. I now have the Hydroboost master mounted and the lines connected. I did have to massage them to fit, but the larger one still goes to the forward port. I also found an article from GMHTP on the conversion that looks like the same m/c. Larger line clearly goes to the forward port. Thank you, Turbonut!! I do appreciate it!

Is yours an 84-85 as this would make sense as it didn't have a powermaster.

The late production 85's had powermaster.

So he has a late 85? Then I would say it odd that the brake lines lined up when swapping from powermaster.
