TiMopar Posted June 28, 2017 Report Share Posted June 28, 2017 Hi, my 72 510 needs a new ignition switch ( the collar type which grips around the column ). There is one on E-bay that has an inside diameter stated as 38mm, however my old one measures 40mm. The fact that the E-bay one has a measurement listed suggests to me that there may be different diameter columns. Can anyone confirm this? Thank you in advance : )) http://www.ebay.com/itm/LHD-MODEL-38MM-IGNITION-SWITCH-STARTER-KEYS-SET-FIT-DATSUN-BLUEBIRD-510-/152602221973?vxp=mtr&hash=item2387cd1d95 Quote Link to comment
LenRobertson Posted June 28, 2017 Report Share Posted June 28, 2017 I measured both the column in my '72 510 and an extra column from a parts car 510 (which I'm fairly sure was a '72 also). Both measure 38mm diameter. These are US spec left-hand drive cars. I don't know if there may have been a different diameter column for other countries or for RHD. The eBay seller mentions the ones he is selling are for LHD model so maybe there is a difference there. If you have just a bad key switch, those are available I believe. Len 1 Quote Link to comment
TiMopar Posted June 28, 2017 Author Report Share Posted June 28, 2017 Len, thank you for the reply. My car is a US spec LHD car, so I think I now need to measure the OD of the column to check what's up... Thanks again! Quote Link to comment
LenRobertson Posted June 28, 2017 Report Share Posted June 28, 2017 I was curious about measuring the column if I couldn't find any calipers around here (tools often fade into the parallel universe although they generally return when I no longer need them). I doubled over a length of masking tape so the two sticky sides stuck to each other (only so the tape didn't stick to the column). I wrapped the tape around the column and marked the joint where ends of the tape overlapped. The circumference of a circle is pi times the diameter. So 38mm times 3.14 is 119mm. When I laid the masking tape out flat and measured it I got 120mm which I think is close enough considering I wasn't being extremely careful when I wrapped it . Maths is fun when it works.

D52E Posted June 29, 2017 Report Share Posted June 29, 2017 I got 38mm as well.1969 510 on left and 73 240z on right. Both 38mm. I seem to recall 280ZX had a smaller diameter 2 Quote Link to comment
TiMopar Posted June 29, 2017 Author Report Share Posted June 29, 2017 Thanks chaps for taking the time to reply. I am now convinced that this is in fact the part I need and have ordered it, fingers crossed : )) Quote Link to comment
D52E Posted June 29, 2017 Report Share Posted June 29, 2017 I found my 280zx switch. It measures 32mm. 1 Quote Link to comment
