Question for the purists

[lowrollin70gmc]

I say add whatever you want, but I’m not a fan of adding to the SPID. My reasoning is that you may be honest when you sell the truck but who knows what’ll happen 10 years down the road after a few sellers.

I would rather not have an SPID than an altered one , but I do like the asterisk idea, so you have all the options on there, but it’s clear that they aren’t factory.

I like this for mine:

6BTA Cummins Engine System*
NV5600 Six Speed Manual Transmission*
...

*Accessories installed after OEM delivery*
