Introduction

Note: All measurements are in inches unless otherwise noted.

This article will be divided into at least three sections

The first section will list wheelbase, front track and rear track of vehicles in inches, so that those interested in frame swaps or clip swaps can find the correct donor vehicle. Dimensions will be listed left to right as wb/ft/rt followed by the year, make and model of the vehicle. For instance: 86.0, 50.6, 50.3 -- 1952 Morris Minor. If one or more of the dimensions are unknown, NA should be inserted in that space. For instance, if the wheelbase of the Morris were unknown, it would be listed as NA, 50.6, 50.3 -- 1952 Morris Minor. If the wheelbase were known, but the front and rear track were unknown, it would be listed as 86.0, NA, NA -- 1952 Morris Minor.

Guide for taking measurements

Wheelbase is the dimension from the centerline of the front tire to the centerline of the rear tire. Track is the dimension from the centerline of the tire tread on one tire to the centerline of the tire tread on the opposite tire on the same end of the vehicle, front track or rear track.

The second section will be listed as axle flange to axle flange where the wheel bolts on. Drum to drum would be close enough to the same if that's all the information you have to post. The only difference between the two would be the thickness of the material of the two drums at the studs.

The third section will list backing plate to backing plate on the rear differential. This information will require knowing the width of the brake drum to determine flange to flange dimensions. Find brake drum width, multiply X two and add that figure to the plate to plate dimension to get flange to flange.
