So for those that are not already aware, here is a list of cars to check out in the wrecking yards for different gear selection.
10 bolt Toyota rear end parts can be had from the wrecking yards.
Try these:
1974-79 Corolla SR5 w/5 speed
1984-87 Corolla GT-S
1971-85 Celica ST,GT
1971-73 Carina
1970-71 Corona 4 door
1972 Corona
1973-74 Corona HT Sedan
1975-82 Corona
A bit more info that may be of interest to our street legal friends:
If anyone is looking for specific gears at the boneyard - look for a
'76 to '81 Toyota Celica. Look on the engine side of the firewall for
a 2"x3" metal plate with codes as per the following table - only pull
the driveshaft off to look at the pinion nut paint color to confirm
that's what you really want. The only way the codes are wrong is if
someone swapped the rear end out for a differnet ratio. Most
everything you'll find seems to be the 358's, though I've found a 342
and a 373.
T412 is a 330 - orange pinion nut
T382 is a 342 - purple
T372 is a 358 - pink
T302 is a 373 - red
T312 is a 390 - yellow
T292 is a 410 - green
T282 is a 430 - blue
330 celica liftback
342 earlier corollas
390 " "
358
410 earlier corollas
430 later models of both with overhead cams
How To Read The ID Plate:
On the tag, there is a code number which is the very bottom line. It may be something like:
147FT11T052W55 (example)
In those numbers, the group that is "T052" in the example identify the ring gear diameter and gear ratio. The digit "T" identifies it is a 6.7" diameter ring gear (10 bolt). An "S" code denotes a 6.38" ring gear (8 bolt). You will want the "T" code.
The second and third digits of this group - 05 in this example - identify the gear ratio. the list below are the most commonly used:
Code Gear Ratio
02 3.36
05 3.70
07 3.90
08 4.11
27 3.36
28 4.30
29 4.10
30 3.727
37 3.583
38 3.417
The fourth digit - in the example a "2"- designates the number of pinion gears and whether the rear end is limited slip or open traction type. The possible codes are:
Code # of Pin. Gears Ltd. Slip (yes/no)
2 2 no
3 2 yes
4 4 no
5 4 yes
So, in the above example, "T052" designates that this car has a 6.7" ring gear with a 3.70 gear ratio and has 2 pinion gears and is an open traction type of rear end.
Limited slip is hard to find, and expensive! You may want to consider an open differential vs the spooled or welded spider gears for street use. It's more an ease of driving deal.
In racing legends cars, the rules are pretty strict. It is a spec class, after all. Rules don't even allow these cars to be made street legal!
You can also use these cars for things like a parking brake (or emergency brake) if needed.
Anyway; I hope this information will help some of you.
