I haven't looked that hard for the 2.125 pots which are the standard XKE Series 1.
My problem is I'm trying to find 2.25 kits which are really difficult to source.
I have some information on what cars used them (Datsun and Toyota) but there are contradictions:
The 2.25 Datsun is the 311 roadster 1969 only according to the information I've dug up. However, when I check the on-line 311 parts catalog, its the same part number for ALL years.
So I'm not even sure what Make/Model/Year came with the 2.25 pots.
It seems like the few places that have the 2.25 are very specialized shops that look at these pots as a special upgrade - no mention of what the OE application was. This is probably for 2 reasons: the Japanese cars that used them have all rusted into dust leaving only the European cars where they would be an upgrade.
The Toyotas are hideous Crowns and Coronas however the Datsun is the 311 roadster. I probably should focus my investigation in the 311 camp since I think the Toyota is dead.
Of course RockAuto has nothing for these old Japanese cars - and RA is notorious for closeouts. (nothing for XKE in closeouts either but with RA, inventory changes constantly)
