I have a 91 RS with stock 2.73 w/Drum brakes. And i want to do a full 3.42 Disk brake swap.
Does the higher gear throw off my spedomiter? and a new driveshaft?

Its a 5-speed Too

 

yes, speedometer gears will need to be changed. The driveshaft will be fine.

 

If you don't mind the rear wheels sticking out an extra 1.5 inches on each side, the cheapest easiest way to get this is a 4th gen rear from a 1998+ F-body - nice big LS1 disc brakes and 3.42 posi's are easy finds for about $250, and a direct bolt in (just have to do some rigging on the e-brake cable).

 

Following is general info about 10-bolts and all that you need to accomplish a swap, to include master, proportioning valve and e-brake cable.

BTW, Camaronewbie, Ed Miller now has custom cables for the LS1 swap:

Here's a link to T-5 speedo gears and a how-to for install:

where are those located?

 

Check the last link I provide. BTW, you'll need to swap both drive and driven gears.

random question, i have the ebrake cables from the 95 camaro, but i think they are about 3 inches shorter than my original ebrake cable.
should i just modify the original cable?

 

It would have been better to start your thread. Or even better, do a search since this has been covered. Like maybe in the 4th gen axle swap threads?

Anyways....You can cut both & splice your 3rd gen cable to the 4the gen cable, or buy one specifically made that way. I don't recal who. but I know at least one of the TGO sponsors has them.

 

Personally, I'd purchase the correct cable. Check the first link I provide for the info you need.

id like to but im on a budget, cant afford 100$ cables

 

RockAuto has them for $20.79 per.

wow, thanks alot man. You sure there 1434mm?

its a 91 RS

 

Rockauto sells the adapter cables?

 

Oops, 91, my bad. Check to see if you have the tunnel-mounted adjuster. If so, you need the first design. If there is no tunnel-mounted adjuster, you need the second design. Check post #4 of the following link for a pic and info:
