Hey folks,
I posted this question a while back over in the 60 section (I've got a stock 1981 FJ60), but decided to post here, too, since I haven't made any progress and was hoping that some of you all might be familiar with the large cap dizzy...

Toyota lists the 2 Governor Springs for the 1981-87 FJ60 2F large cap distributor as NLA:
part# 19154-61102
part# 19153-61102
Does anyone know:
1) if the OEM parts are still available elsewhere?
2) what the spring constant for each of these OEM springs are?
3) if there are aftermarket springs with the same OEM spring constant that will work?
4) if there are aftermarket springs with similar spring constants that might be an improvement?
I'm trying to adjust the ignition advance curve because I'm seeing full 38* advance before 2000 rpms!! So if anyone has been working on DIY improvements such as changing springs or weights for adjusting advance rate as a function of rpm, I'd be interested in hearing any suggestions you might have...
Thx.
