My wife and I are big fans of your Youtube channel, as you explain things very clearly and easily. We also live in Houston as I understand you do. Question for you:
We have a 1989 Alfa Romeo Spider Quad and when shifting gears, it grinds like crazy. It initially started only in 2nd gear but now it does it in all. I believe the problem is with the clutch master cylinder and/or clutch slave cylinder. Can you give me your opinion, please?
Thanks so much! Look forward to hearing back from you!

sure, change the cylinders first, and pray it's not either a worn out clutch or worn gears inside the tranny. those old alfas tend to be money pits.
