1/72 scale Vietnam stuff

If you are looking for helicopters, you can get just about every one used in Vietnam in 1/72.  Can you narrow your request a bit ar give us something else to go on?  Any particular type you like, Army, USMC, Aussie, VNAF, etc.?

There are lots of armor and a few figure sets that were used in Vietnam in 1/72 as well.  Again, you need to narrow your focus some to get some answers. 

This is what I have either piled up or in progress:

UH-1B/C/D/E/F/H/L/M/P   (Haven't decided on the N yet)

AH-1G/J (need help with Anti-Strella kit)

SH-2 (wrong variation- want either a good one or help to revert to early variation) 

HH/CH-3

SH-3 (looking for a better version and also info to make "Chink 69")

OH-6

OH-13

CH-21 

UH/CH-34

CH-46

CH/ACH-47

HH/CH-53

CH-54 (going to kitbash with a 53 kit)

OH-58A (have one from Italeri but not pleased with it)

Mi-8 (just need markings)

I guess that just leaves the rest of the Mi helos the north flew and then for the U.S and VNAF side:

H-19, Allouettes, OH-23, the ever so difficult CH-37 and anything else someone can tell me there is. Remember 1/72 scale only

I have a 1/72 scale Hasegawa AH-64A Apache sealed to trade if anyone is interested.
