Were the pumpkins red oxide from the factory? All the one\s I've seen were all rust/ grime covered. Just curious

I think they were all painted black, I'm just using up some red oxide primer I had laying around.

I love it when guys take the effort to detail the stuff they're repairing anyway. That is NICE!

I installed the upgraded rear axle in jazebelle today. It went well and made a noticeable difference in performance.

The speedo is off by a good margine now. Does anyone have a speedo pinion gear for a 727 to sell ....? It's a 31 tooth, green, part number 2538931.

Good job Stan!

 

[commando1]

You're welcome.
Yes, you really need to take your tire size, calculate the diameter, then work backwards to pick the correct gear for your rear end ratio, Since it will be pretty hard to hit it dead on, use the Miata calculator to determine the %-age it will be off by and to get the smallest error. Under 5% and you're doing good.

Too much work... just drive it

GPS speedo is the way to go.
