Default Couple of questions on third gen swap

I have a 91 Firebird V6/AT......


OK: I have this stuff down:

-LS1/4l60E
-Motor Mounts
-4L60E Crossmember
-Fuel Pump
-Fuel Lines
-LS1 Ac Compressor
-Cold Air Kit
-Radiator(Will a 4th gen radiator fit???)
-Speartech Wirng Harness

Is this about it???

What am I missing???

Also, What about tranny mounts??

What will have to be reprogrammed in the ECU???

Thanks

Exhaust system.
Throttle cable.
Fuel pressure regulator.
Radiator hoses.
Relays for fans, fuel pump (may be part of Speartech harness?)

That's all that comes to mind, dig thru John Bzdel's site and the month-by-month links to see if you get any more ideas.

I went with a Lokar cable, only modifications I had to do were:

1.) cut off the clevis end and put on a plastic cup to clip into my car's gas pedal.
2.) two big stainless steel fender washers + rubber washers to mount on the firewall.

Might have been easier to use a 4th gen throttle cable, but you'd need to drill oversize the firewall hole and bend the gas pedal arm.

for a throttle cable, get one out of a late model chevy 1500 or 2500 with a 5.3 or a 6.0 because they have the manual throttle you need, and it also fits in older throttle position hole in the firewall. Thats what I did for my swap into an old blazer.
