VIP Weekly Fun Question for 3-24-2012

Specifics on the VIP Weekly Fun Question (VIP WFQ) can be found under the "Important Threads" section of the Weekly Fun Question Forum.

This week's VIP WFQ is meant to "piggyback" on a query earlier in the week whereby a Member was looking for a driveshaft for his Mustang. The question is designed to magnify the fact that there were actually different driveshafts utilized during the production of the 1971 - 1973 Mustangs.

The Question:

Please identify which of the following application has the longest driveshaft as original equipment.

a. 1971 Coupe with L-Code, 3-Speed Transmission, 28-Spline Yoke, 3-inch diameter driveshaft and 3 15/32" Rear Joint

b. 1971 Convertible with F-Code, 4-Speed Transmission, 28-Spline Yoke, 3-inch diameter driveshaft and 3 5/8" Rear Joint

c. 1972 Mach 1 with Q-Code, C6 Transmission, 31-Spline Yoke, 3-inch diameter driveshaft and 3 5/8" Rear Joint

d. 1973 Fastback with Q-Code, C6 Transmission, 28-Spline Yoke, 2 3/4" diameter driveshaft and 3 1/2" Rear Joint

Good Luck!


The desired response is "A."

The 1971 L-Code (250 1V) driveshaft, along with that of most of the 302 equipped 1971 - 1973 Mustangs shared a length of 51 3/4 inches.

The 1971 F-Code (302) Mustangs with 4-speed, along with the 1971 - 1973 F-Code Mustangs with 4-speeds, and 28 spline yokes shared a driveshaft length of 50 21/32 inches.

The 31 Spline, aluminum case 351 4V for 1971 - 1973 Mustangs shared a driveshaft length of 47 7/32 inches in length.

The 28 Spline, C6 351 1973 Mustangs, along with the ones for 1971 and 1972 Mustangs shared a driveshaft length of 50 13/16 inches.
