T56 Magnum in 69 Camaro with Holley LS swap

[69Camaro]

Hi guys,

I'm looking for recommendations,

I work at a GM dealership and got a great price on a GM Performance Magnum T56. Now, I have the transmission, Holley LS swap kit including crossmember, aluminium bellhousing and LS7 clutch and GM throw out bearing.

I am fairly sure I will need to cut the transmission tunnel. I will also need the clutch master and bracket/linkage. I want an SFI bellhousing and will need a driveshaft and small parts (reverse lockout, wiring connectors etc).

I will be running a GM 525hp LS3 and ECM and a Moser 12-bolt.

Who has the best parts or kit currently and best customer service? Price is an issue but secondary to customer service and quality.
Any advice or prior experience is helpful.

I did search but going 3 years back I didn't find much solid info on kit quality, fitment, parts availability etc,

Thanks in advance,
Jayson
