Hey all-

Just wanted to share my 75 dollar 90x mile tranny. Thank you pick and pull half-off day!! Great for the budget enthusiast. I hope I can get the conversion done in June. Also, anyone know a good driveshaft shop in Sacramento?

One other thing... when did they stop putting the boat anchor diff. in the 02s? I thought they were only in really early cars, and my car is an actual '71 (according to the VIN) and has no evidence of being tampered with (like the cut-in-half M3 from the roadfly boards or something terrible like that) but I wonder why someone would go through the trouble of changing it out. I think it's a 4.10 rear end, perhaps that was why, but it's a bit tall. What would be involved in correcting this? I know the driveshaft must be changed, but what else would I have to do? It may not be all that bad, but the clutch is so worn out I can't really rev the car up. It's weird what people will do to cars after 30 years.

end of Dec 1968 production. If your '71 has one, it's been fitted (along with the proper rear subframe--they're different) from an earlier car. That's kinda unusual. 1600s switched over to short neck diffs at about the same time (don't know the VIN) so most 69s--and all the later 1600s had short neck 4.10 diffs.

I'd be kinda surprised if you had a long neck diff in your car; it's quite a bit of trouble to swap--subframe, driveshaft etc.

They had inserted the car recently, I had been out there a couple weeks ago and I just saw it. There's a set of BBS 13's laying on the ground out there too, I've just been too lazy to round them up.

Which, according to what I've learned, is a US-spec 71 2002. I don't really know why someone would swap out the diff as well, maybe more acceleration? It still doesn't make complete sense, if they made the short-neck 1600's. Oh well, it works, so I should probably leave well enough alone. :)
