Should peddle arm be heated in bending to make inch adjustments . Or can they be bent while in the chassis without heating. Having trouble installing wood toe board and peddle arms are not lining up with slots in the rubber bumper plate or the rubber bumper stops.
I guess the first question is what pedals are you using and which ones don't align? If they are stock 32 pedals, they should line right up. If they are later pedals (anything that didn't come in the car), then you'll need to heat them with a rosebud to bend them.
I think as a rule of thumb, you should always heat a forged metal before you try to bend/ straighten it. And always let it cool by it's self. Quenching it in water it cause to become very hard and brittle.
