Nah, what he means is your tire size, not wheel size. The important part is how tall your tires are going to be. Example: z 275/60-15 tire is 28" tall. This could affect your gear ratio choice compared to say using a 31" tall tire.

El Camino rearend is not going to bolt in a truck.  It is a car rear end and has a different bolt pattern.
