Astro Van Hyroboost Threads

[airbur]

Does a one know offhand what the threads are on the booster unit? Both the firewall bolts and Master Cylinder bolts. Thanks

Found them. Here they are in case anyone else wonders:

1/2-20
and
9/16-18

Thanks for updating this with what you found Airbur, I'll be needing this info eventually.

Well, I was wrong. The specs above are for the ports on the Astro Van's master cylinder......something else I was looking for also.

Still need the threads on the booster bolts. May just take the thing to Ace and test a bunch.

There ya go. When in doubt that's usually what i end up doing.
