Wow, that was the easiest thing I've done!
I have to admit, I watched the video 10 times.
Wrote down what I had to do on paper with steps.
Went through the steps in my head before I did it.
Performed actual steps.
Done.
It literally took less than 60 seconds.

Excellent. Got a link to the vid you watched?

I'm looking at getting some bigger tires soon and I need to replace some bulbs in the cluster so might as well do it all at once.

I was wondering about that, been thinking of upgrading from my stock 15 inch rims.

Lol if only that worked for the old analog speedos lol. I know mine is off right now with the 265's I have on stock was 235. I assume it will only get worse when I put on the 33's this summer.

I know my speedo is 10% off, when the speedo shows 60mph, I am doing 66mph
not a big issue for me. I am not sure if I may ever put the stock tires back on.
also figuring gas mileage, I add 10% after calculating
