EB48.3 or .4????

[BulldogSRT]

Hi,
I am new around here since I just got my first Tekno. I picked a used EB48.3 off RcTech, but I am alittle confused? It was sold as a EB48.3 but looks to be a EB48.4. It has the correct front, rear, steering parts of the .4 but I am not sure how to check for the difference in the chassis. I will have to wait until I pull the diffs to check the tooth count on the ring/crown gear. Any ideas how the .3 and .4 chassis are different? And how I can verify the chassis

Thanks,

Tons of ways to tell the difference, but here is the quickest that I know at just a quick glance:

EB48.3 rear arms are flat across the bottom:

EB48.4 arms have an extra protrusion where the shocks mount:

Thanks. Is there anyway to check the differences in the chassis. So far it is a EB48.4, only 2 things I am not sure on is the diff's tooth count and the chassis. The diff gears are pretty simple, but the chassis I couldn't find much info on.

the milling is different on the aluminum chassis particularly around the servo mount, you can compare any 2 parts you want on TEKNO's website:
