Leslie,
I just replaced my old AI and DG. I used Sigma-Tek for the DG, but had to 
use RC Allen for the AI. Reason: The Sigma-Tek AI is too long and with 
fittings will not fit between the panel and the nose fuel tank. The RC 
Allen fits nicely. Also, make sure you install a filter. Most of the
Alon's 
did not have an in-line filter for the vacuum instruments.
