On my 86' Regal with a 200R4 trans does anyone know what the length of the speedo cable is from the trans up to where it mounts here?

Unfortunately, no. What are you trying to do with it? These were originally 2 piece cables, an upper and lower section. Two part numbers were used for MW9 transmissions. the 95 inch CC1120 (25033563) was replaced with CC1066 (25033391) at the end of 1987. Strange, since the July 1987 parts book shows CC1120 for 84-87 MW9 in the G-body, and the CC1066 for 1988 G-body. Whatever. Anyway, both were 2 piece units. I have a few of the 1120 cables still in the box. If I can remember where I have them, I'll drag one out and measure it.

Just needed the length on the lower one, when I went to undo it from the trans the end spun on the casing instead of unscrewing but it is still intact and I screwed the adapter cable for the trans lockup into but wanted to have a new one on hand in case there is an issue.

I think the issue you will find is that unless some aftermarket company makes a lower section, you may be relegated to buying a new cable.

FYI, at least from Delco, you can't buy pieces/sections of the casing and cable. In 2002, the newest supersession number is 88959481 (Delco or GM #) came along. It's 100.9 inches long. But it's NOT a 2 part cable. It lists from GM for $60.39. Rockauto sells them for $24.79, or around 23.50 with the discount code. Figure their standard 7.99 shipping and you're at $31.50. There's one on ebay for about 4 bucks less.

When I first looked at it I thought both ends were female but I just looked it again and the upper end of the lower cable is actually a male that would explain why the replacement cables listed seemed too long but obviously they go all the way to the back of the speedometer.
Thanks, I appreciate your insight on this.

I've always tried to understand WHY they thought a 2 piece cable was a good idea. There must have been a reasoning for it, but I can't come up with a good one. I mean, the replacement cable that they finally ended up with is a 1 piece, and I know the 1 pieces I've had on A-bodies (68-72) were long. So thinking that with a 2 piece, they'd be less likely to barber pole in the casing - but that doesn't make sense either. If the end of the casing is bad, you're going to need a new entire cable. Which sucks. Sorry man.

By-product of the rising popularity of Cruise control, perhaps?

I thought that as well, but they last used a fender mounted transducer (2 separate cables) in 1983. The 2-piece cable was used from 84 through 1987. :unsure:

Additionally, even if you took the cable apart, I don't think the top section would be long enough anyway.
