Early 1200 had 45mm ones from memory. The stanza etc had 51mm struts. As we didn't get a-4 or a15 from factory in b110 or b120, makes no difference based on engine.

Yes it looks like the A12-models had 45mm strut and most A14/A15 had 50.8 mm strut.

What did Australia have? In USA all have the larger strut even the A12 models.

Both of those are 2.0 inch tubes (B310 and 180B/610). That converts to 50.8 mm. The smaller diameter tube is 45mm, as used by B110.

There are two different B310 struts which are 50.8 mm. Is there also a 45mm B310?

Stanzas are 51mm tubes.....
They take the VL Turbo calipers or other calipers with 76mm bolt spacing.
There are two different 180B stub axles, a small bearing and large bearing type. The smalls are the same as Stanza and (I think) the original 1200 stubs.

The ones I have are 49mm tubes which is the same as stanza, 200b's ect as far as I know. The sunny stuts have the smaller springs though which can be helpful. Could make for some easy brake upgrades if so. Stanza and 200b front ends are getting a bit thin on the ground these days.

B310 Sunny came with two different size struts. I believe one is interchangable with A10 (Stanza/Violet/510). The other is probably not.

Does anyone know if sunny struts will take the hilux calipers and stanza discs?? I can't find any info to say they won't but I haven't heard of anyone running this set up??
