I have just been through this 

The answer to your question is the bent pushrod booster hole is 9mm lower the the straight one 

i hope that makes sense 

i have both here 

Cheers Kevin

The pedals i have the stop light tab thing is welded to the front of the pedal for the straight rod booster 

 

The pedal for the bent rod booster has it welded on the side 

 

dont know if they are all like that but could be a way of telling them apart ?

Yes that is correct 

You need to weld up the old hole and redrill 9mm lower 

Centre to centre of hole 

 

The pedal in the above post on right is for a bent rod booster

I only have bent pushrod type here and I measure the manual one at 73mm from pivot bolt centre to pin centre.

The auto pedal I got from Ebay looks to be h series Holden now I look closely but the torana auto pedal would need to be the same pin position or it wouldn't line up.

Here's and old thread.

Looks like I got 71mm not 73 back then.

I'll go check again.

Bit tricky to measure accurately as the old bushes have a bit of play. I'd actually say 72mm after checking again.

If you need more accurate, I'll have to remove the bolt and bushes and measure inside diameters etc and calculate the actual distance.
