We had 32 of these made years ago for our SCCA E-Production 356 race car. I've got 3 complete sets left (+3 ind. stacks). They are spun from alumunum and the measurements are as follows:
bottom: 47.25mm / 1.860" OD
45.18mm / 1.767" ID
top: 77.13mm / 3.036"
height: 121mm / 4 13/16"
We had these comissioned for Solex carbs but should fit anything with an adaptor.
$55 each / $200 a set
Fed-Ex Ground freight included with insurance and a tracking No.
