Progress on the Merkur!
So I bought a V6, realized I was retarded, and stopped that nonsense. Building the 2.3 up as God intended.
I have a handfull of odd and ends for my T5 swap; I got a Turbo Coupe WC T5, 2.3 Mustang bellhousing and clutch fork, and the Rapido crossmember. Pretty much the only things I need now are a new pedal box, a clutch kit, the 2.3 clutch cable dogleg nonsense, and a driveshaft.
So, I called Rapido. They want $700 for their two-piece, which is supposedly the greatest thing since sliced bread.
I found this guy: Merkur Depot, but his $300-ish driveshaft is out of stock. Given the guy has a page listing current events for '07, I'm not holding out hope. (His intercooler setup is boss, though. Is this guy still in business?)
Then I looked through old GRM threads, and apparently 460 Machine makes a driveshaft adapter that lets you bolt up a 1 piece Fox Mustang shaft without any modification. This is convenient, as one of the local yards has a 4 cylinder Mustang that NOBODY has touched for months. Still had the full drivetrain a few weeks ago, including the T5.
I know some of you have the adapter, and I'm just curious how it does in the wild. Is vibration a problem? Will it hold up to the torques? Is it worth $120?
