sourcing replacement spring hats

[rallysprinter]

After pulling down my struts from my AE86 rally car, I've found I've got broken spring top hats. hat_underside_vsmall.jpg

Hoping someone on here can identify what model the spring hats are from and where I might be able to source replacements from. I've been told that AE86 have a D shaped hole but these may be drilled out as I have aftermarket struts. Toyota have confirmed that AE86 spring hats are NLA.

My problem is that the springs are what look like factory size (90mm inside diameter and 115mm outside diameter) and all replacement spring hats I've found are to suit smaller diameter springs.

Any suggestions?

If you look on inside of strut leg i.e inner face on outside of strut tube just below lower spring seat you should see the Toyota standard part number. Then go to toyodiy.com or partsbase.com type that number in and should give you model of car they are from. Then search for spring top hat number.
Once you find part number for top hat go to amayama.com and search part number and if available will show availability and price. I have dealt with them many times, freight may be a bit slow otherwise very good to deal with.
