Got a Key made on Samba to fit our ignition and door locks for $20.00 . We should have gotten two of them but wanted to make sure it fit ok. Just gave the guy the code on ignition and he had it done in a day. Heres his link if anyone needs keys or needs to find there key code . http://www.thesamba.com/vw/forum/viewtopic.php?p=5910088&highlight=#5910088
yeah it should be the same dash bulbs as a 74, and yeah 1157 bulbs works for the rears,
Or you could just use a flywheel and slide it on the output shaft. Mark with a pen where it hits, and remove a little material. Repeat till the flywheel goes on all the way. Much easier than installing and removing the motor...
