you'll have to fiddle with the part's config file (rescale factor). I don't think I'd have the permsission to upload my modified versions unless I ask the author

I also had to change the location of the stack connections so the capsue would acutally fit. a lot of trial and error was involed.

makes copies of the parts and rename the "name" and "title" so you know which is which in game.

Heatshield

// --- general parameters ---
name = ThorHeatshield2
module = Part
author = Yogui

// --- asset parameters ---
mesh = model.mu
scale = 1
rescaleFactor = 2

// --- node definitions ---
// definition format is Position X, Position Y, Position Z, Up X, Up Y, Up Z
node_stack_top = 0.0, -0.6, 0.0, 0, 1, 0, 1
node_stack_bottom = 0.0, -0.7, 0.0, 0, 1, 0, 1

Capsule

// --- general parameters ---
name = ThorCapsule2
module = Part
author = Yogui

// --- asset parameters ---
mesh = model.mu
scale = 1
rescaleFactor = 2

// --- node definitions ---
// definition format is Position X, Position Y, Position Z, Up X, Up Y, Up Z
node_stack_top = 0.0, 0.69, 0.0, 0, 1, 0, 1
node_stack_bottom = 0.0, 0.55, 0.0, 0, 1, 0, 1
node_stack_2bottom = 0.0, 0.65, 0.0, 0, 1, 0, 1

...

MODULE
{
    name = ModuleDecouple
    ejectionForce = 10
    bottomNodeName = "2bottom"
}

chute

// --- general parameters ---
name = ThorParachute2
module = Parachutes
author = Yogui

// --- asset parameters ---
mesh = parachute.dae
texture = parachute.png
scale = 1.0
rescaleFactor = 1.2

and was for the KAS crane, just rescale that to 0.5. rest is trying to put it together.
