Heater hose diameter : 1974 body, 1971 engine ?

[Bergo]

Hello folks,

Hoping someone can clarify for me. I'm wanting to reinstall heat in my car, it's currently disconnected and missing most of the ducting. I'm going to place an order to aircraft spruce for some SCEET tubing (double wall silicone hose), but wanted to verify the diameter I should get.

1) 1971 engine, and matching heat exchangers: 2.5" diameter from engine tin to heat exchangers, and heat exchangers to flapper boxes?

2) in the boot, is it all 2.5" hose from the heater channels up to the front flapper boxes, and the boxes to vents and fresh air blower?

Hoping I can get away with ordering a 10' length of SCEET and use it for everything.

input much appreciated! (and my apologies, I know there are several threads about backdating heat, and what tubing to buy, but I found it really confusing as to whether it's the same across certain model years)

Mine is an 82 motor in a 71 body. I used the same duct for Aircraft Spruce throughout, from fan to ssi's and from the air handler in the frunk to the body.

Sorry, I don't. I can measure this evening and post.

Edit: A quick search tells me 2.5" (SCEET -10) is correct.

I ordered 10' of -10 SCEET from aircraft spruce, will report back how it all fits!
