Engine swap changing coils, What size / type coil? Options

[jsaum]

I'm in the middle of an engine swap and am so close to getting my car on the road I can barely stand it! I'm putting a 1.8 motor from a 75 into my 72 and found that the size of the coil that normally mounts to the engine tin is different from the one that has the bracket that mounts on the blower housing. Does anyone know the correct part number or coil to use for that mounting bracket?

Thanks,

Jsaum

Look up on the engine tin. You'll find two holes with weld-nuts. Those hold the original coil bracket onto the tin, at least on earlier cars. (I think some of the 1.8s had the coil where you show it? But I'm not sure.)

The bracket that comes with the Bosch blue coil does not work with those two holes, unless you are willing to use and trust some very large fender washers. The new bracket is shorter than the old and the holes don't line up very well at all.

I used a piece of bicycle inner tube wrapped around the coil to get it to fit the old bracket. It has worked fine for many years. I have heard stories of duct tape adhesive softening over the years and allowing the coil to move around.

I'm using the engine tin from the 1.8 so it doesn't have the holes to mount in the other position. The engine is already in the car or I would just swap them out. I'll figure it out in a few days and post more pictures. My problem is the coil is to big and the clamp won't fully cover it as I would expect. Once I hook the clamp into the blower housing and hinge it over the coil there is a distance one to one and half inches from the bracket to the housing.
