thank you for the information and the advice, gentlemen.

I removed the dash and found an old punch card taped to the back of it. Is there anyone that knows what it means?

it is a 78 f100 2wd, 300, c6. wheel base is 133in. another question. the badges say custom but any time i look for parts online, ie. jegs or summit, the L6 is only listed under base. are the badges wrong or the websites not educated?

Gentlemen,I am new to changing out U-Joints on my drive shaft. I removed it with little difficulty, the u-joints gave me some trouble but got them out. Upon further inspection, it looks as though I have two different sized u-joints. The front one is marked with a "130" and I could not find any...

Finally got around to changing the transmission fluid and filter. Drained and refilled the TC. First time doing it so I was a bit nervous. Went pretty well but its still having issues shifting. Thinking it might be the modulator. We will see after tonight.

thanks, fatherdoug, i am by no means an expert mechanic. more of a DIY learn-as-i-go type. i learn something new every time i get on here.

i had a similar issue with my 78 f100. it could be something as simple as a loose ground or it could be a bigger issue, possible a neutral safety switch.

Thanks for the advice. For now I am going to have to stick with the stock rims and cheaper tires. No point in spending money on great tires when there is such a long road ahead in way of repairs.

I am trying to figured out if 17x8 wheels with a backspacing of 4.5 wrapped in 255/75r17 would work on my stock 78 f100 custom. any advice?

Finally, got the passenger door swapped.
