67' Speedometer cable firewall hole question

[Brandan]

From what I can understand the '67 automatic and Saginaw both used the same firewall hole for the speedometer cable is that right?  I have a pic of my firewall and want to double check.

That's correct - every transmission except the Muncie used that speedo cable hole.

Do you know the correct length for the automatic T350 speedometer cable?  I also believe that it routes under the frame kind of like the parking brake cable and turns toward the center of the car.  I want to say that the length is aroun 69 inches.... but not sure....

thanks

Now I read an archived post that the short cable was used 28".  Now I am more confused.  I think the AIM shows the cable goes around the bottom of the chassis (like the parking brake), so I would think that the longer (69") cable would be correct.  Any help on this one.  Also where can I get one?

The speedo cable routing is shown in your Assembly Manual in UPC 12, sheet A3. The TH350 wasn't available in 1967 - don't know which cable length is correct for it.

Thanks John, you wouldn't know the length of the powerglide cable would you?  I have checked everywhere I can think of........

thanks John, close but i found it on C3.  Looks like the manual and auto are the same???

The 28" cable is for cruise control K30 option. UPC K30 A3  #7- 3919007.

I am coming up with either a 58 inch or a 69 inch cable, at least narrowed it down somewhat.  Still not sure which one is correct.  I looked at all the parts dealers and with so many different cables it is easy to get confused.  Also Bob thanks for the post.  Unfortunately I don't have cruise.

This is my 1st post, and I have been reading the comments on the speedo cable.................
I have a '68 RS/SS 396 with the Muncie 4 speed. Rolling bare body shell. I have noted the speedometer cable hole per the AIM for the big block,(under wiper motor) but I have no reference to the exact correct length of the cable. Does anybody have any info on this??
