Can anyone tell me what the size of a stock '91 N/A steering wheel is? 320mm, 350mm, 360mm? What sort of challenges are associated with changing the original for, say, a Momo wheel? Thanks

 

Not sure on the size, but you basically pull the old one off and (with the correct boss kit) bolt the new one on. If the old one comes off easily it's a 5 min job. I just yanked repeatedly (and swore some!) until it popped off. My Momo is only slightly smaller OD than the stock wheel but because it's a nice thick rim, the ID is quite a bit smaller. As a result I can't see the top of the tacho, the important 80-120km/h part of the speedo and the indicators! Most annoyingly, my carefully positioned 50mm VDO boost gauge (in front of the stock boost guage) is now half obscured! Luckily it's only the vacuum half.
