ok iam planning to buy a rear end for 200 dollars that came of a gsl first gen . will the posi track bolt up right away ? do i have to do any modifications? will the gs drive shaft bolt on directly to gsl rear end ? i want the extra power because i like to touge with my friend who has an sr20 det on his 240 .

 

Yes. You could just swap the pumpkin.

 

depends on the year of the gsl rear vs your rear (axles might be different). I am installing a 82 gsl rear in my 85, and have to swap the whole rear (and use the 85 driveshaft flange). I am still looking into the brake lines.

 

well the rear end comes with the pumpkin , axles , disc brakes and calipers. soo am i complete ? or do i have to buy anything else

 

might want to think about replacing bushings while you have it all tore up. if the years are the same it should be a strait swap.

 

Ahhhh, disks.
I think the proportioning valve may need to be changed, as well. (?)

 

You may want to consider the GSL rear caliper emergency brake cable assembly.

I am doing the swap to my '81-GS using an '83 GSL rear axle assembly and this is the final component to purchase before I implement. I am still cleaning / painting my stuff, atm. It's all ready; looking quite pretty, except I am considering new front calipers / turning front rotors, too, as I'll be bleeding brake lines, anyway. Git 'er done!

 

the good o' axel swap. i must've done it 4 times.

heres a check list for the swap to make it simple:

proportion valve
rear end
ebrake cables
brake line splitter valve to the rear

redline diff fluid + additive
brake fluid to bleed brakes

am i missing anything?

 

how often do u have to change the fluid for the posi rear end? is it alot of maintence

 

Am I wrong to assume that we can use the '81 -'82 brake pipe valve with the '83 GSL system, as well as use the '81-'82 proportion valve hardware? I've done alot of reading on this subject in alot of forum discussions, but have yet to do the actual swap, myself. I plan on getting good photos and do a write up as I do mine as a reference for others.

 

I'm interested also, as I have the complete 82 gsl rear axle assemble (with disk brake hardware) that I got from a junkyard. The e-brake cables are cut, so I am guessing i need new ones (or can I use the ones from my stock 85 drums). I did not know that a proportioning valve was necessary, but it makes sense. It looks like I need the new cables and proportioning valve, but what is the splitter that was discussed above?

 

is 200 dollars too much for the rear end with the disc or is dat a good price . and quotes on it

 

i paid $250 so $200 is good but i got screwed also...because the brake calipers are seized and they just cut the lower bar that mounts the rear end so im going to reuse mine i have now....
