Do I have a sct410 or 410.3

[teknojim23]

I bought a used 410.3 apparently. When I looked at the manuals online mine has the 410 front bumper. What is really weird is it also has the 410.3 center diff cover. Very strange. What is the easiest way to tell the 2 apart?

Pill inserts on the SCT410 are oval with only 3 tuning positions per insert:

For the SCT410.3 the pill inserts are square with 9 tuning positions per insert:

Thanks it is in fact the 410.3 but strange it has the old front bumper.

I was never a fan of TEKNO front bumpers and always ran TBR bumpers which drastically improved durability:

Unfortunately TBR went out of business during COVID and I am not aware of anyone else making comparable bumpers, but you can improve durability of the stock bumper by making a custom brace that attaches to the front center brace on the steering plate in the same manner of how TBR did it. Simply buy some 1/8" Kydex and cut/shape with a micro torch to heat the plastic and bend to shape:
