Hello Guys
The toyota rears are a great swap, and we have run them in our drag cars for years with great results.
There are two types of toyota rears that you want to use.
one is the 1979-1995 4x4 trucks 6lug, the other is a 1982-1991 1ton 2WD 5 lug they both have 30 spline axles which are almost unbreakable.
The 4x4 from 79 to 1985 is a leaf spring rear so you have to cut minimal bracketry and it measures 55" from WMS to WMS (wheel mounting surface) the 86-95 4x4 are 58" from wms-wms. The jewels are the 1ton 2wd wich are all 4cyl trucks that came factory with a 4speed tranny or a V6 2wd, they are also 30 spline and measure 56 1/2 long from WMS to WMS. (same width as a 1st gen )
Both these rears are 8" ring gears and have a removable dropout or pumkin/center section. Gears are available from 3.42 to 5.77 Spools & posi units are also available.
Want more detail?
The 85 and older rears (55") are best for drag racing due to the fact that the upper control arm will have to be straight as apose to an angle on the stock upper trailing arm. (the bearing cup is long and will not allow you to weld the brackets to close to the axle. So if you want to use the stock brackets and arms from your 1st gen you will need the longer rears from a 86-95 4x4 wich is 58" similar to a gsl-se lenght..
oh and you will have to re-drill the axles to your bolt pattern which any machine shop can do.
the rx4 is much easier since its leaf springs.. any toyota will do but i would go with the 55" narrower rear for wheel backspacing.
Hope i was able to help Guys
God Bless
