Does any one know if a LS1 driveshaft will fit with no problem in my LT1 Camaro.

 

It'll drop right in. Keep in mind that it's not very strong though. It's fine for most cars but they have a habit of turning into pretzels when using slicks at the drag strip

 

Where is the best/cheapest place to find a 1LE driveshaft?
Most of the ones I have found have been carbon-fiber.

 

Definately go 1LE , they are nice peices, I have the LS1 in my 93 so I bought the 1LE for my 97 to see the diff and it is huge!!! The 1LE is made by spicer, has solid U-joints and the yokes apear to be billet.
I paid 239 @ 10% off at my local dealer.
