Installing manual rack in 951
I know i need to use the lower steering shaft from the manual rack also, but how hard is it to pull/install the shaft on the 951? seems like it would be a bit tricky to get a wrench under that heat shield and all

Remove the brake booster heat sheild and it is a snap. Drop the rack out of it's mounts just enough to slide the shaft off...

Seriously, I don't know. Never had it out. Sorry.

It can be reached with some creative extension work and maybe a second person under the car with a wrench on the nut. See if you can get a long long extension down over the clutch master/under the brake booster. I think thats how I did it, but I might have had the clutch master out.

don't you need different tie rods? it seems that the tie rods from manual (read: early cars) would be shorter.
i've got a buddy that wants a manual rack in his 951S and we need to know.

i did it when i did my rod bearings, so i already had the crossover pipe off and did it from underneath. the top joint is a real pain to get at no matter which way you go. if you have a manual rack from an 83, which seems to be the most common, you need the early tie rods (i think they're longer, not shorter?). i have heard there are late length manual racks, but they're impossible to find.

thats why i asked, the 88 951 is late offset, but your 86 is early, so on your car the '83 rack should have bolted right up. on this car, we want to install an '83 rack as well, so we'll probably have to find some appropriate tie rods to make it work... i'm aware of late model manual racks, but those i believe are ultra-rare... but i understand several guys have put these racks into late cars. late model cars have smaller offsets, so the hubs are further out from the centerline of the cars because the wheels have less meat on them so to speak, so therefore the tie rods need to be longer to reach the spindles.
IIRC, it should be only tie rods that are different - are those part numbers on tifo's list? i've got the rack and the intermediate shaft, it's going to need new boots, and from what i understand here, different tie rods - what we really need to know is the part number of the tie rods that will reach on the late car.
thanks!

Lots of good information here ---> 944 Power to Manual Steering Rack Swap
To convert the 944 to proper manual steering takes somewhat more than simply disconnecting the pump and fluid lines. This method works, but the ratio on the un-assisted power rack is wrong and extremely “heavy”. To do it properly, you will need the following:
1 manual steering rack, part# 944.347.011.00
2 manual rack inner tie rod ends, part# 944.347.033.01
2 manual rack outer tie rod ends, part# 944.347.333.01
Drivers side and passenger side rack boots, part#’s 171.419.831.c and 171.419.832.c respectively
1 manual steering rack intermediate shaft, part# 944.347.027.01
I sourced most of my parts second-hand from various 1983 model year 944’s. This article concerns doing the rack swap on a 1985.5 944 (“early offset”). The procedure is basically the same for all 1982 thru 1986 model year 944’s, including the turbo models (the only notable difference on these models is the brake booster heat shield which gets in the way during intermediate shaft removal and replacement). Post 86 cars that have “late offset” share the same basic procedure, with one exception being in the parts list mentioned above. Post-86 cars have longer outer tie rod ends. For these you would need to source part# 944.347.033.03 from your local dealer, or custom aftermarket units from a vendor such as Andial. At this time, I would also like to comment that used intermediate shafts usually have a slight bit of play in the u-joints. If in doubt, purchase this part new (available from www.944online.com and www.paragon-products.com ).
