7 Stack clutch .076 steels I'm going to use the recommended 7 stack 3/4 clutch set up in my 2001 4l60e, below are the 0.76 steels I can get here in New Zealand.
Will these work in a 2001 4l60e or are the 82 to 93 steels different.
77114 ...................... Steel, 700-R4 3/4 Clutch .076” 1982-E87 (Can Use 74114A)... 8678054 120.
77114A.................... Steel, 700-R4/4L60E 3/4 Clutch .076” L1987-1/4/93 (W/Notch) Retros To 1982........ 867177010
Or do I need to pay extra and get Kolene steels for 82-Up
77114AK.................. Steel, 700-R4 3/4 Clutch .076” (Kolene) (Hi-Performance) 1982-Up ............
going off the part number I would guess they would fit, but nothing for GM is cheap here, so I would like the to get the correct parts 1st time.
your knowledge is much appreciated.

You'll want the 77114A, 20 Tooth .076" steel, so that the steels work with the 4L60e 3/4 release springs. The other part # without the 'A' does not have the notch to accommodate the springs.
Your # for the kolenes look to be correct too. Just make sure it is a 20 tooth steel.
At first I did not recognize those part #s so I did a search and found them sold through a different company. The numbers I reference below are from Transtar and are the ones I am familiar with.
Transtar # for 3/4 steel .076" is a 74120A. It has to have the 'A' so that they work with your 3/4 release springs in a 4l60e.
Transtar # for kolene #steels are 74120AK .076"
