Help with Power brake conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I got a complete power brake booster from a 73 GMC and put it on my 74 Chevrolet. It bolted up fine, but when I tried to slide the PB rod onto the brake pedal it wouldnt go. I then looked at the manual master cyl and the hole is bigger on the end. Do I need to get a booster from a 74, or do I need to get a PB pedal assembly? I was going to drill the hole out, but there is not enough material on either side to allow that. I thought this would be a smooth bolt on, but guess not.

Thanks,
Keith
