The short answer is 'yes & no'.
The '71-4 B-body pedals are not a bolt-in, mainly because the large housing for the pedal assembly is different than E-body.
In most cases, the pedals are also slightly longer than E-body, but that doesn't prevent their being used.
The good news is that if you can get the B-body pedals inexpensively, you'll have everything you need to convert your E-body pedal housing.
In making sure it's complete, these are the parts you're looking for:
- clutch & brake pedals (and the pads should be trapezoid shaped, not rectangular). If you have later pedals, you can either use the later pads or grind the metal down to fit the earlier pads
- long pivot bolt & locking nut that the pedals ride on
- 'outrigger' - the triangular bracket that supports the long pivot bolt on the clutch pedal side
- over-centre spring & pin (1/2" diameter metal rod). As others have pointed out, if you're using a diaphragm type of clutch such as a Centreforce, then the over-centre spring is not required.
- optional: clutch safety switch & hardware
If you are in need of the pedal rebuild parts (new pads, bushings, bearings, up-stop bumper etc) I have some surplus kits here that will be less than ordering from the USA. Plus cheaper postage and no HST. PM me if you're interested please.
Good luck!
