gauge sizes

[charlesratcliff39]

Guys I want to buy aftermarket gauges for my truck and need suggestions and the sizes of the gauges .

I used Auto meter. The 3 3/8 are drop ins in the big holes and the 2 1/16 fit the smaller hols with a little die grinder work. The vac guage reguired a little more grinding but not alot. These are all electric gages so if your going to use the speedo cable you'll need a mechanical gage.

Beuford I have one more question can you use a electric speedo and how do you use it in place of a mechancial .

[Beuford]

I put a `90 5 speed transmission in my truck and it has an electric VSS so I had to go electric. They make mechanical speedos that match their gages either mech or Elec. I know I've seen an adapter to go from mechanical to electric not sure where.There is an electric to mechanical adapter here.
