I'm a new guy looking for help about starters
I have a 2004 Silverado 1500 4.3 V6 which I am in process of swapping out for a 2003 Yukon 6.0 in it. I have seen that I need a spacer in between my crank and flywheel to be able to use my V6 4l80e transmission but does anybody know do I use the V6 starter or do I need a special starter?

But if it is a 4L80e, yes, you need the flywheel and spacer (except the early 99-00 6.0 that already had the longer crankshaft, those don't need the spacer.) You can get the ATP version. I used that one on my 4.3 to 5.3/4L80e 99 Silverado. You can get it at the parts store. Use a 2001-2006 suburban 2500 6.0 for parts lookup.
Source a starter for a 6.0 LS as well; the V6 stater won't work on the 6.0.

You should have a 4L60e on your 1500. Are you sure it's a 4L80e? The 80e only came on 8 lug trucks in this generation (except the Hummer 2).

This is the spacer that I have for it.

I meant a v6 4L60E sorry. This lq4 has a short crankshaft with a dished flexplate and I'm not sure if I need my spacer that I got for it or use the spacer and that dished flexplate?that's why I am confused because if I use the spacer it moves the flex plate further away and I don't think my 6.0 starter will work.
This is the spacer that I have for it.

Here's an article I always refer to when this question comes up:

Maybe source a starter from an Escalade. Those had the nearly identical LQ9 and a 4L65, both are pretty much the same dimensionally to your setup.

Actually this come out of a 2003 GMC Yukon with a factory 4l65 all-wheel drive and is only three holes in the flex plate. I've been told since the V6 4l60 has a shorter input shaft I have to use a spacer but I'm not sure

The transmission input shafts are all the same (in this generation of trucks). The input shaft of a V6 4L60e and input shaft of a 6.0 4L65e are dimensionally the same.
According to that article I posted earlier, all you need is the dished flex plate with 11.066" bolt pattern. If I understand correctly, the dished flex plate and the LS style 4L60e 300 mm input shaft/torque converter (which you have) basically locates the starter in the "normal" position.
Does that make sense?

All the 4L60s are the same sort of, input shaft is the same though

Yep, agreed.
The 90s 4L60e were the ones that had different input shafts and torque converters. IIRC, there was a 245, 298 and 300 mm input shaft version for I4, V6 and V8, respectively. Something like that. That all got condensed into the 300 mm version at least in the GMT800 trucks as far as I know. The 4L60e from the Atlas I6 mid-sized SUVs (Trailblazer, Envoy, maybe the S10 too?) have some internal differences compared to the full size truck 4L60e. Or so I've read on the LS1tech forum.
Not sure why I just stated all of that. Doesn't apply to OP. 🙄
