'73 pedal swap

I'm going to do a 5-speed swap to replace the auto in my '73. I found a '77 280 with a 4-speed at the local Pick-N-Pull and I took the clutch and brake pedals along with all the hydraulic stuff.

I quickly checked my 240 the other evening and it looks like the pedal mounting is different than on the 280. Can someone confirm this. Do I need pedals from a 240 and not a 280? I hope not becuase it was a pain getting those darn things out !!

Thanks
