4 Bolt Questions

[blackmirage]

So, I've been told and I've read here, that it is a good idea since my car will be strictly a race vehicle at the track.. that a 4bolt rear end would be essential unless i want to break stuff. So, I want to know two things, one what years do the 4 bolts come on, I've searched and looked and looked maybe not in the right place but its been about 30 min and still nothing. Also, is it a good/decent idea to try and find these rear ends in a junkyard, or just look someone up on the trader? Thanks in advance guys.

How can I tell if my car has a 4-bolt rear end?

According to the staff of Conicelli Mitsubishi, all 1G cars produced before the second week of June, 1991, have 3-bolt rears. This essentially covers all 1990 and 1991 DSMs. All 1992-1994 cars have 4-bolt rears.

Many DSM owners are under the mistaken impression that the changeover between the original 3-bolt rear end and the stronger 4-bolt version occurred halfway through the 1992 model year. This is not so.

Those curious to know the production date for their car can check the driver's side doorjamb sticker. The acronym MDH stands for month, day and hour of production.

This is not entirely accurate. My car was produced Jun 13 of 91 and has a 3-bolt rear.

I looked in the FAQ, didn't come across the 1000 already answered questions. Didnt come up in any of my searches- sorry.. Thanks for the info though, We have like 3 93 eclipses at the yard, so I'm going to take a look and see if they still have the rears..
