Hi Terry and All: I don't know the "gauge" of the 300F battery cables, but they are very close to 5/16" in diameter, insulation included. One thing I do know for sure: Antique Auto Battery doesn't seem to be able to even correctly copy ones sent to them! I ordered a set for the 300F and the ground cable for the 300K. 1. The overall diameter on the "repro" cables received was about 3/8"---something like the size the earlier Chrysler cables would be. 2. Lengths were not the same as the samples I sent. 3. The positive F cable has the direction of the clamp reversed! 4. They used an almost indescribably ugly rubber grommet to "finish" off the end of the wire loom where the starter harness approaches the starter relay. In other words, there was something wrong with everything. Did I get back with them like I should have? No. I guess I thought it probably wouldn't be worth the effort. I had talked to them on the phone several times, and sent them original samples with plenty of little notes attached describing details. Giving up seemed the right way to go at the time. I am using the F stuff temporarily. I cut off the ugly grommet and used it as an exhaust pipe isolator repair in the our van! Thought that was appropriate. I then made what I think is an acceptable wire loom end by utilizing the largest diameter heat shrink tubing I could find. I think it looks pretty good too. So that is my story on AAB. I am sure many of you have had much more positive experiences with them---at least I hope so, but thought I should relate mine. Forewarned is forearmed, so they say. 300ly, Gil Cunningham Tally, FL In a message dated 5/1/2006 8:40:25 PM Eastern Standard Time, pennsy300@xxxxxxx writes: I am going to order new battery cables for my 300F from Antique Auto Battery, here in Oho. Does anyone know the gauge of cable used in the originals?
