You guys with headers in shock tower cars, are you using all four mounting bolts or just side two bolt locations and/or along with top bolt ?

That bottom bolt in my 63 Fairlane is a real mother F#*cker

I have a C8OA-7515-D clutch fork for big shaft input , originally for a 68-69 428CJ.
Would this also work without modifications on a 1970 with a 429 and toploader with original 429SCJ bellhousing ?
I realize ford made a different fork for the Boss 429 , but how was it different from a 69 428CJ fork?
Length? specific bend? clip location?

thanks

That method also works for Shelby Cobra replicas and Fox Mustangs...

It's pretty universal.

For the record, the original image I referred to in my question was from Shelby American in the 1960's at their shop.
Thanks for the confirmation folks, it eases the dread having installed and removed the headers the hard way too many times.

I can't take the credit, somebody on the old forum told me about doing this so I tried it.  Worked really well, of course...
