Re: Will 1999 rearend fit on my 68
it's probably over 3" wider minimum. 71-87 length housings increased by 1.5". 88-98 (GMT400) housings increased again by 1.5". Seems I recall the track width increased for the next generation GMT800's as well.
That being said, anything can be modified to 'fit'. It just depends on what the application is.

Re: Will 1999 rearend fit on my 68
You wrote ‘suv’.
Which one? Some are narrower than stock 68. |

Re: Will 1999 rearend fit on my 68
If it’s free why are you asking?? What’s the harm in picking it up and seeing if you want to go thru with it. Width aside you’ll have to strip the perches and shock mounts off the axle and the re weld new perches and shock mounts once you get the pinion angle set. It’s not very hard.

If you're not sure of the SUV ratio, remove the cover and take a picture of the numbers stamped on the edge of the ring gear.. We'll be glad to tell you what's the actual ratio... |
