I put an 85 AOD in my 53. I want to use my original Speedo. It looks like the housing that goes into the Transmission will fit but the teeth on the gear are angled the wrong way. I have 3.78 gears in the rearend. does anyone know what speedo gear or cable I should use? Or any of you who have done this, what did you do?
This is what you will want http://cgi.ebay.com/ebaymotors/Ford...ccessories&hash=item2a09305da3#ht_1633wt_1165 I use a 23 spline with my 4:10's The cable for a 1969-70 Mustang with 302 and C4 will have the correct ends and length.
