Brake booster differences

R&R of entire brake system on a 1970 GMC 2500
While I expected it to be a bit different, the length of the rod to the interior pedal on the new looks short.

Ideas appreciated.
Thanks much...don t.

Re: Brake booster differences

That booster just doesn't look right for a 72.

Isn't it adjustable? Most aftermarket jobbies are.

Looks like a '67-'70 dual diaphragm Bendix. Some '67's are a little different, don't have the reinforcing tabs welded on the back half. These are for 4 wheel drum brakes. Factory disc brake booster/master cylinders are different, and use a different length pushrod. Be careful, using the wrong push rod = no brakes!
