Got a Dorman drive shaft from Rock Auto yesterday

My original shaft is 2" diameter tube. Rock Auto's Dorman description says 2''

The shaft I received is correct part number on the box, 938-192, but the shaft is a 2 1/2" diameter tube

Im going to take other measurements, the the cardan diameter , bolt pasterns, etc.etc. for comparison.

Anyone else have a 2 1/2" Diameter front drive shaft on a square body?

I have turbo 400 auto , original TC , all original
