What size aftermarket gauges fit in 69 Cluster?

[sdkar]

I want to add either silver or white faced aftermarket gauges on my 69 Camaro Pro Tour.  What size gauges will fit in the round part of the cluster.  I was going to go with a Covan setup but decided to copy the Reggie Jackson Camaro and use the stock console with aftermarket gauges and keep the stock gauge bezel.  Also, any ideas or links to check out for buying these.  Who makes nice gauges?

Thanks,



Steve
