Making my own coilovers.

[Whizbang]

Here are the stock stats i measured out:

FB:
5.5" stroke
1.8" (45.6mm) OD Tube
32.9mm insert body
20.9mm insert shaft
1.0mm x 42.5mm (or maybe 41mm?) depends if you measure the inside or outside of the threads) Gland Nut

FC:
?? Stoke
2" OD tube
34.64mm Insert Body
22.65mm insert shaft
No Gland Nut (welded cap)

So from the above information, i am trying to build two different front sets.
First set is for an FC subframe on my FB. The body is the right side for easy to find threaded sleeves for the springs (2") but lacks a gland nut. I am pretty sure i can cure this via welding the threaded section of another tube from another car. namely rwd toyotas. I need more stroke with the car anyway so i can have a longer tube body. Insert wise, im pretty sure i can use a Bilstein insert. Might be pretty straight forward.


The second set is for my FB. I want to use the FB tubes since it uses a gland nut but the inserts leave me wondering. I really have no idea what there is for inserts that could fit in there. It has a narrower tube as well at about 1.8" so not sure what kind of threaded sleeves there are.

There other thing is can i remove the strut tubes from my 82 and use them with 84/85 spindles? I can see how they would come out.
