Not I but I bet you can do it with air cleaner top, corragated intake tube and coolant tank removed.
Getting that allen wrench socket, extension and ratchet in above the brake booster is the trick. Getting the aluminum foil facing on insulation around booster pushed out of the way will be helpful.
I just removed cable on car I parted out. It maybe helpful to loosen the four nuts under the dash holding brake booster so you can jiggle around booster to get a little more room to access allen head bolts holding accel cable housing to firewall.
If all else fails and you can pull the cotter key and clevis pin out of booster rod at brake pedal you can then push booster and master cylinder forward and down enough to gain more access the cable bolts. Just a thought not an easy one but one just the same.
Some cars may have hex bolts instead of allen head ones.
