Great thread, read it from start to finish last night. I'm getting ready to do the same thing to my 87 van. The new trany is sitting in the garage right now.

In the very beginning I saw you check the angles of the drive shaft, but when you put it back in I didn't see anything about duplicating those angles. It is very important to do that. Check out the video its the only place I've seen it explained. The below code should take you to it. If it doesn't start playing click the "embed post" button in the lower left and then preview it.

Hi Doug
Must have forgotten to post, yes I did check the angles and they are spot on, so all lined up correctly. Have had a "LONG" unplanned break during the build but back on it again now as just want to get it finished and getting so close now!
Problem is you take one step forward and ten steps back as its a custom install and I am finding my way with every step, now stuck on the carb linkage no idea what I should have there, members have kindly posted about the two brackets i need but i like to see a photo of what I need and match to it, just sitting here now trying to find the illusive pic incorporating the part numbers listed.!Even e-mailed Holley but no reply!
Glad you enjoyed the post I hoped it would be of use to others, any questions at all feel free to ask and I will gladly help if i can!
Regards
Mark

Political correctness is a doctrine fostered by a delusional, illogical minority, and rapidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by a CLEAN end.

Hi All

Still working on sorting the linkage out have established that I am a spring missing (consisted of an inner and outer, I found this laying on top of the manifold when I brought van and have put it somewhere safe! but can I find it I am still looking.

Have chance to get the kickdown linkage below pretty reasonable anyone know if this will be of any use to me as I have no idea?
Thanks
Mark

3pinplug, I'm not sure how that apparatus would be adaptable to your application. It looks more like an accelerator pedal linkage to me, likely with the intent of a spring attaching to the flange-headed pin at the top of the L bracket. The two vertical facing holes in that big dogbone don't look like the sort of geometry used on the transmission or the intake manifold.

Getting this to work will very likely consist of lots of fabrication, cussing, and throwing of tools... I'd think you'd do better to save up for a cable system that's designed for your van or refurbish your original linkage.

Looks like a bell crank assembly for part of a kickdwn linkage, but the action is wrong to use it aspart of a mechanical kickdown linkage. It might work with a cable style kickdown linkage, but if you are going with a cable style kickdown linkage then you can just connect it straight to the carb and skip this bell crank part.
