427 AIR Adjusting Brace

[Tim S.]

Can someone tell me the length of the 427 AIR Pump adjusting brace?
I know they are different from the 327 brace. I am looking to buy an original one and I found one but cannot tell if it is correct it is ~11" tip to tip.
Thank You

Attached are photos of an original GM #3921903. It has a developed length of right at 10-1/2".

Joe thanks for the pic. I am not sure of developed length but I assume that is end to end on a plane. It is hard to tell as all I have is a pic
of the one for sale but and they look the same so how long is the small block adjusting brace and are they the same shape?
Thanks

Developed length is the length of the part if it was flattened and straightened. It can be measured using a string or tape.

The small block brace has less of a total off-set than the big block. However, it's GENERALLY the same contour as the big block with two offsets. While I have several of these, I can't get at them right now to measure. My vague recollection is that it's a bit longer than the big block.

The small block brace is MUCH easier to find than the big block.

Joe that is OK, Paragon sells the BB one for $45, apparently they are slightly shorter with a different bend as you indicate.
Not worth taking a chance on an original since they have no ID markings as I underdtand it.

Thanks for your help
