It was the same when i was looking could only find 2lt dohc
Thats why i paid over the odds for mine when i found one (£400
But it was a 1.8cvh with only 65k all documented so i just went for it
In any other circumstances i wouldnt dream of spending that on a crusty sierra but when you think of all the parts you get from it, it is worth it especially on a low miler.
Get your wishbones now and just keep on looking, im sure if one pops up after you have spent the money on wishbones you will still find the money to buy it
As people always say one will pop up when you least expect it
Are you looking for pinto or cvh or either?! i will keep my eyes peeled
