1968 Fiat 850 Spider

[speedracer835]

I fabricated the Transaxle front mount our a a piece of 10 awg sheet steel. It is a cut shape with one bend. I designed the mount to bolt to the body under the sway bar mounts. I added a 3/4" wide strip of 10 awg steel along the edges to make the mount ridgid. Two hole are match drilled to catch the factory transaxle mount.

I made my half shafts out of one vw half shaft assembly that I cut in half. I then measured to the Fiat hubs to get the required additional length of each half shaft (note: I set the motor 3/8" off of the centerline of the car, to allow the transaxle to go between the rear suspension mounts withiout any modification ) I added the required length of material using a piece of 4140 steel shafting. If I was to do this again I would cut the Fiat half shafts to the required length, but I wanted the ability to got back to stock if my conversion didn't work out.
I keyed the 4140 shafts and the original Fiat axle bells.

The rear engine mount is nothing more that a length of schedule 40 pipe with two hanging tabs welded to catch the upper two bell housing bolts. The ends of the pipe will require a piece of angle iron the will sit on top of the body frame section in the engine bay.

As to additional parts..
You will need a VW shift lever and the rod that connects it to the transaxle.
I made a flat plate the sits between the shifter and the hand brake. This plate hangs two bushing brackets the the shift linkage passes thru.
I cut the VW shift linkage as required to add 2 standard 3/8 ratchet swivels.
The leading swivel is just aft of the brushings the other swivel is at the end of the linkage and is drilled out to recieve the transaxle shift rod.

Conciderations:
You will not have a speedo drive on a vw transaxle. therefore no speedometer. (I am working o a solution)
The hand brake will require a rocking bar to be added. (I have designed but I have not installed one in my car as of yet.
I used a "Freeway Flyer" transaxle in way car. Vw wheels ar 15's while Fiat uses 13's.
If you use a stock transaxle you will lift the front of the car! and be out of gears at 50 MPH.

PS you will love this conversion!
Go to your local Fiat club and spank those snooty 124 guy's.

Thanks so much for the response sorry i am so late seeing it. The project had disappeared until just last week when the current owner of the car decided he really didnt want it anymore and is going to give it to us for free.

i has a full roll cage installed already and is fully stripped all lights are removed as well as the dash and the windshield frame. The owner claims all it is misisng is a 850 shortblock and that it has heads everything else. So far my research has been unable to locate a shortblock so the VW route is looking more promising.

thanks again for the run down Daled you wouldnt have any pictures of the mounts would you?

thanks for the info i typed up a long thank you earlier today and it didnt get posted so this will be much shorter

the car we are picking up has no motor but has several pro built heads and has a gearbox of unknown condition.

the car is fully gutted and has a full rollcage installed and the windshield frame removed but there is no major rot in the subframes or suspension pickup points just minor surface rust on some of the body work.

it has been lightened to the max everything uneeded removed. the Vw conversion looks like it wont add much weight

the plan is to autox it in DM so i would like it to be under 1280lbs after the swap.

do you have pictures of your mounts? and do you know how much your car weighs?

i will get picks of the spider as soon as we pick it up and take it to its new home
