Mark B's Build Thread

Having a small garage for a build does indeed suck. I have my lift, which is great, but there's not much room to work.

Hoisting the spider up to the ceiling is a bit of a trick as a one-man job. Through some creative use of pulleys, though, it's up there. When I'm ready to take it back down, I'll be using neighbors and free beer though!

Installed the rad and fans. I used rubber grommets to isolate the rad. I still need to hook up a ground strap.
I decided to cut a ridge into the fans to lock them in to the rad frame on the top edge, with bolts/riv-nuts on the bottom. I had to trim the shrouds on the fans a little to make them fit cleanly, but they seal up completely to each other so no leaks.

For the steering wheel, I went with the NRG Gen 2 quick release and short hub. I had that setup on my Corvette and it works great on the street and track.

There have been several posts on here about using the new NRG177 hub (for C6 / Caddy columns). For those with Fran's newer kits, the racks he's now shipping actually use the older style column shaft, so the NRG170 is the correct adaptor to use.

Of course, I realized that after I already bought the 177, so Alex got himself a decent discount on that one :)

Once I had the right one install was a breeze. The rack didn't have the airbag clock spring, so the hub went right on. I got the plunger wire for the horn as well, so once I power it up, I *should* have a working horn...

Hi Mark. It was me that you sold the NRG 177H hub to. How do you get the horn button to work in the steering wheel without the clock spring installed? The clock spring is used for more than just the airbag. It transfers all the electrical connections to the steering wheel.

What make of car was the newest version of the steering column from?

Sorry Ken! I was going back through some notes and for some reason thought it was Alex.

On the older style GM column (like the one shipping with the kits now), the horn doesn't use a clock spring, but a contact disc with a plunger that sticks through a plastic housing. They used a separate clock spring for the airbag connection.

Unfortunately I didn't take pics of the plunger setup, though.

I'm pretty sure it's still a GM rack, but I'm not sure what year/model it's from (i never bothered asking Fran). GM and Chrysler used the same steering wheel hub design for many years.

Knowing which make and model would be really helpful. I just found the tilt feature on mine LOL.

Would like to make a pull for it or get one from a junkyard.

Guys,
the electric column is NLA from GM...I purchased everything GM had in inventory a few years ago , and we have used them all.
The new column is much the same from a functionality point with the OEM switchgear but is now manual tilt only.. It is still a GM column from an Olds/Buick...but I was never informed as to what particular model.

Hi Eric,
I actually found an extra pull handle for the tilt column in my box of small parts. If you PM me your address, I'll send it over to you since my column already had the lever.

Yep, you have to drill and tap the holes. I used Allan's video for reference. It was pretty straightforward, but drilling that first hole in the beautiful new upright was a bit nerve-racking :)

Mark can you find any GM part numbers on the steering column. If so I'll find out what cars they were installed in and post some schematics for anyone needing to do some diagnostics/trouble shooting in the future.
