TR3 Autometer Guages

Hi everyone!

I may be purchasing some Autometer guages as part of my "slight engine
modification" project.  I love the Carbon C2 version but have 2 questions
for you clever folks -

1) Will the 5 inch tach and speedo fit into the TR3 dash (I think so)
2) Where is the cheapest place to buy them online (I've new the rodding
side of things)

As always,

THANKS!
