O.K. I'm getting ready to do the 5 lug conversion on YellowDog. I have a 68 SC front end and I am going to re-drill the rear hubs. The question is what do you that have done this recommend; press in studs or bolts? If studs, where did you source them and if bolts, how long? I have a set of BBS style wheels that came off a 68 SC 'I think'. Also if I go with studs, will I need to machine a 'flat' on the back side of the hub so they seat?

Studs. Yes, a flat. Not enough meat on the hubs to get more than a couple of threads, and you need at least 14mm of them. I got studs from Performance Products last time I needed them, but they were extra long. Perhaps some of the usual USED sources might have them. You need the thickness of the hub, plus the thickness of the wheel at the bottom of the ball seat, the thickness of the lugnut (approx 14mm), and a few threads beyond that. The Cap'n

I'm no place close to a 911 expert. 68 is what I was told they are from. Can anyone give me some visual clues to look for? I have entire front end from the donor car.

Call GPR and get some Verbus studs. Nice quality and cheap. Or maybe HPH has them.

'68? See the current thread about that. You don't really want to install a '68 front end in a 914. You will have to use the whole front end, and it's a downgrade, practically speaking, from what you have. The Cap'n

About all I can say right now is that the Bilstine inserts that were put on YellowDog a few months back fit the 911 struts that I have, they are five lug and have cast iron calipers. Can anyone provide some numbers that might be cast on the steering rack of calipers that might shed som light on the exact year of the parts we have?

Here is a quick pic of the 911 stuff. Can anyone tell what year they might be from by this picture?

OOPS! Sorry! Not SC, but somethong in the mid 70s. Has the mounts for the early bar, but the largish calipers. SCs have the bar below the A-arms. The Cap'n

As far as I can tell, that's prolly '69 through '73
The swaybar mounting tabs on the a-arms are a give away for "through body" style swaybars which were only used up to 1973 (although some one may have added them to use after market swaybars) The steel crossmember means pre SC *I think* IIRC the SC and 3.2 Carrera came with an aluminium x-member (but I could be wrong in that they were only used on 3.2s) You could measure the spacing of the caliper mounting bolts. If it's 3" it's pre SC struts, if it's 3.5" it's SC or later... The mounting carriers on the front of the a-arms are '69 and on, so at least you don't have the real early (SWB) stuff This should bolt up just fine... cheers, Jeroen |

Just order the redrilled hubs/studs from GPR. If you ask they will press them in for you for free (they did for me). You send them your core rear hubs and they credit you the core charge.

Anthony, do you remember how much they were? They don't list them on their web site. I can do mine for free, but if I can get them done with the correct studs installed it might be worth it.

QUOTE(anthony @ Aug 27 2004, 06:04 PM) Just order the redrilled hubs/studs from GPR. Or look here in Product Resources for redrilled rear hubs. I bought some for Eric Shea and I must say they are extremely well made. |

I can't remember how much but the hubs weren't the expensive part of the project. It's all the little stuff that adds up (brakes hoses, pads, rotors, bearings, etc).

SC has aluminum I beam crossmember. May have started a little earlier. The 911S (early 70's) had 3.5" caliper spacing.
On the rear, the early911 (same as 914-6 I believe) hub and CV is splined same as the 914-4 axle. Save the rear parts, as with parts from the 944 you can do the entire rear to five lug, brakes too I believe. My memory is a little vague on the exact combination. |

GPR charges around $75 to have them redrilled. Or they have the complete kit for $325.
(IMG:style_emoticons/default/stromberg.gif) !.asp?http://www.gprparts.com/item.wws?cookieID=788295924&sku=914352916kit&mfr=GPR" target="_blank">http://www.gprparts.com/brands/gpr5LugKit/...2916kit&mfr=GPR Eric Shea also has them for $425 but thats a complete bolt. A better deal then GPR too. |

IRRC, the splines are different, so you'll need 914/4 stubs redrilled, or 914/6 stubs and hubs. The Cap'n
