86 & earlier T5 gear ratios

I've never been able to reconcile the '86 and earlier gear ratios based on the gear sets I've seen advertised for Ford T5s. I've had a look inside my T5 and here's the results.

Input shaft: 21
Cluster, input: 37
5th: 59
3rd: 32
2nd: 23
rev: 15
1st: 14

Output: 5th: 27
3rd: 27
2nd: 31
rev: 32
1st: 32

Rev. idler: 20

The input shaft and cluster input gears are real odd, I've only found listings for them for Chevy applications. The third gear pair are pretty odd for Ford 4 cylinders too. This does add up to the advertised ratios though.
4.03 : 2.37 : 1.49 : 1 : 0.81 : rev 3.76

Glad you confirmed my post. But to add a little more, the 86.5 tranny code changed to -167, as is mine. That tranny code is not shown in most T5 lists. Both the 114 and 167 are WC.

Just in case there's some confusion:

(Cluster input / input shaft)* (output shaft / cluster shaft output) = gear ratio (except for rev idler)

(37/21)*(32/14)= 4.027 (regular rounding rules used = 4.03)
