Different throttle bodies?

[chriscurtin]

Hi,

I was taking apart my intakes today to get them cleaned up for painting and noticed that I have two different throttle bodies. One has an 'S' stamped on the butterfly, the other a 'B'. Also they have different stud/ball locations too:



The bottom one here is from an 87 xr4ti auto. The top one I don't know what it was run in.



Is there any difference in the two? Besides what I noted above, they appear to be identical.

This will be in my 84 RS Turbo if the post/ball position matters by body style.

Thanks,

Chris

Either one will work, you should find one has a shorter "throw" than the other one though due to the different ball location.
