Porsche or VW flanges, 901 trans HELP!

[trevorbrady]

I have a pair of type1 CV sized output flanges to fit a 901 (coarse splines) I will sell if you need them

They are drilled for 6 holes:

Sounds good! How big diam. are they? Because thats the problem here, I need more space to my framehorns. Or what could I use to the flanges I have? I want to keep it as simple as possible. Thanks for all answers, great forum!!

Anyone here who are OR have used these types of flanges in 901 tranny in a type1 chassi? Im afraid that the driveshafts will be too long. What do you think? Hmm

Martin, I tested those 901 flanges in my 915 transmission in my VW chassis using stock VW type1 IRS trailing arms, stock VW type1 drive shafts and stock VW type1 CVs. Everything mated up nicely.

I have since upgraded to the 930 sized flanges which I had redrilled to suit the stock 944/VW type2 CVs, stock 944 turbo driveshafts with early 944 turbo aluminium trailing arms.

I tried to keep everything to standard off-the-shelf parts where possible but I couldn't find a pair of output flanges to fit the 915 transmission that used the 944/type2 CV bolt pattern so I had to have them modified instead.#

just found this pic of the above setup:


(note driveshafts are angled because the transmission was moved forward a bit)
