'68 c30 power brake question
http://m.ebay.com/itm/67-68-69-70-71...257Ciid%253A10
Is this all I need to swap out my manual drum master cyl or is there more linkage involved?

Re: '68 c30 power brake question
I know there isn't a prop valve with it and only wondering if the bracket and rod pictured is all that is needed.

Re: '68 c30 power brake question
Do you have all the brackets and linkage that bolt to the firewall? AND that 10 series stuff isn't going to work on your 1 ton.

The link has a bracket pictured, I currently have a manual master.

Re: '68 c30 power brake question
Brackets look correct. Don't need combo/prop valve unless swapping to disc on the front. You can retain the stock piece

Re: '68 c30 power brake question
Thanks! I have disks up front from an '84, I'll have to source a kit with the larger booster then.

Re: '68 c30 power brake question

No, I only bought the frame and front suspension.

Re: '68 c30 power brake question
I found a kit with an 11" booster, that's the c20/c30 diameter right?

Re: '68 c30 power brake question
I think you might be right, luckily I still have the front stub.
