Yet another 5-lug rear conversion, some questions Options

[TonyAKAVW]

I've been reading up on lots of threads about the rear conversion, CV joints, etc. etc. I'm not 100% clear on everything, but more importantly I'm not exactly sure what I have...

A few years ago I picked up a roller that was in the early stages of a -6 conversion. The owner worked at a Porsche shop here in socal, and had put a 1987 SC front end on the car, and started to do the 5-lug rear conversion.

So what I have are a pair of trailing arms with some stuff installed. From what I can tell from the other threads, I have a 74+ hubcentric wheel flange, early 911 stub axles, and on one of the trailing arms, a partially complete 911 handbrake. The other trailing arm has the dust shield portion installed, but no shoes, etc. The stub axle flanges measure 100 mm across in total diameter (edge to edge).

Now for the questions:

1. There were several threads about spacers required for the hubcentric wheel flanges, but I couldn't figure out where these spacers are supposed to go. Second, is there a way I can tell if this setup has them or not?

2. I'm hoping to use the 944 CV joints, 914 axle, and 911 coarse splined output flanges. Based on what I have are there any issues?

3. Brakes. I currently have the A calipers on the front and stock 914 rear calipers. When I finish this rear 5-lug conversion I will have to choose between upgrading the rears to the V-calipers or moving my A calipers to the rear, and using Boxster calipers on the front. As far as I can tell, there is little to convince me to go with the V-caliper. A set of Boxster calipers is ~$300 off ebay, and I figure I should be able to make a set of adapters on my milling machine. The V-calipers are nearly $600 and offer no change in pad size on the rear. I realize that fora narrow bodied car, the setup I'm proposing is overkill, but if in the future I decide to flare, I'd have the brakes already done. I have a 165 HP Subaru motor, and I'm sitting at about 1900 lb right now, with some weight still to come off. So the question here is any suggestions/opinions?

4. If I do put the A calipers on the back, are they strictly bolt-on or will I need to modify anything?

And be sure and say using the angle spreader, that spreader can be bought by itself as it's also on bmw's, and the support with the rubbing blocks and the 914 extension. For the guys that have the early shoes already they can use them with a small notch ground in them and if they ever wear out then they can go to the 944 style shoes. There is a straight pull that looks very much like the angle pull so be careful on buying the spreaders by themselves. The straight pull, not the early 911 butterfly type, are on the earlier aluminum bananna arms, I think about 74.

I found at least two porsche yards that were very familiar with the individual pieces of this conversion. When I called the yards they said yeah you want the 65-68 911 backing plates off of the steel arms (I don't think there are any alum. ones anyway) and the rest of the stuff off of a 944, it'll take a coupla hours to take the parts off. It was about 160.00 to my door. Make sure you ask for good useable shoes and the least pitted backing plates they have.
