[FirstOwner69]

Disclaimer: I'm certainly no expert on this.

I can't tell for sure from the picture you posted, but the end of your cable that attaches under the dash does not look like the original on my 69 in the photo below. I think I read on this forum that the cable you need may vary depending on your transmission and/or trans. crossmember location. Also, some members have posted that their trucks with TH400s have 2 loops for the cable on the back side of crossmember. However, my 69 has only one in the center... and that's all it has ever had. I don't know if that changes anything though.

Edit- Did you replace all the cables, or just the front? Do you have a LMC catalog? It has a good diagram of the installation.
