Hi,
I have the conversion from Rockland STD gear to adapt a LT1 style t56 to ls1.



What is that smaller race between the new input race and the new input shaft in the above picture?

There were only 2 races in the old LT1 midplate that were close to same size and seem to match the new ls1 midplate


So what is the smaller one for?
Please let me know, looking to finish this this weekend


Also idk if it matters but here's a pic of the clutch and throwout (stock left, mcleod right) that will interface with my t56. Checked teeth and it slides in and out easily.

Also the orange fitting on both slaves doesn't want to slide into the groove cut for it?
Is there a reason or can I just take off some aluminum with a file?
I'm pretty sure I have the adapter for this so it's just uses an fitting instead of relying on taking out that goofy stock fitting.

Please help, thanks.
Also if it makes a difference here's my trans tag# too

Is koyo a good brand for input shaft bearing? Came with it.

Hahahahahaha never mind, it goes inside the input shaft, on the back lol.

My other questions still apply at least.
Also, do you recommend prep clean with non-chlorinated and press on the race and bearing? Or use assembly lube or that fancy lube at my work that they press big bearings on for Allison transmissions?

I have some questions for you if you dont mind, how much the conversion cost you, and which input shaft is the LS1, the longer one?

Thanks.

The conversion cost me 550$, then once you send the LT1 style midplate back (not sure if they want me to send the fork too) you will get the 50$ back. They send you predone shipping label for return shipping.

LS1 style is the longer input shaft.

bringing back an old one, but was this conversion cost including the throwout?

$550 did not include throwout, it includes all bearings for input shaft, the input shaft itself, shims, and plate.

You need to buy LS style throwout/clutch slave assembly(its now a push style instead of pull style), lines for clutch slave (might as well get AN fitting adapter and flexible braided line right away because the stock fitting is dumb), LS style bellhousing, and LS style flywheel and clutch and pilot bearing.

Depending on when your engine was made (or ultimately what driveshaft is in your engine), you might need a spacer either in front of or behind flywheel I forgot.

I believe Rockland or TexasSpeed should be able to help you decide if you tell them what year vehicle you got the engine out of assuming rotating assembly was never swapped.
