| Re: Rearend & Transmission Identification
If it's a 4th gen rear, then it's a 7.625" 10bolt. Should have 28 spline axles and most likely a limited slip.
If the transmission is a 4 speed with overdrive, then it's probably a Th700R4. Could be a 4l60E or Th200R4, but I doubt that. If it's a three speed, odds are it'll be a Th350. Might be a Th400, unless you have some serious motor under the hood....it's overkill.
