Manual to power brake conversion

I purchased an in-line tube brake line kit which was designed for a boosted setting. I installed a power brake booster not realizing that the new push rod location would not match the original brake pedal. I purchased a power brake booster swivel linkage for a 70-74 e body…they don’t seem to make one for an f-body. However, the included piece that connects to the brake pedal is not long enough. Any suggestions on how to connect the old brake pedal to the new brake booster?
