Link tube help me choose from these 2.

[LowBuckX]

Building rear link tubes. I have 2 sizes of 1018 DOM on the shelf at home. 1.250 .212 wall and 1.5 .160 wall.
This will be 3 link with Aprox (on first design) 25" eye to eye lower links and 19" e.t.e odd link..

I would make the threaded adapters myself seeing these are odd sizes to get adapters for. Rubber bushed front eye johnny joint rear eye...


Thanks for any help you can give..
