A friend of mine needs a ignition module for his Rivera T-type. GM doesn't make them anymore. An aftermarket ranges from $650-850. Is the harness and bracket from Caspers the only mods needed to run an 86-87 setup?
That's all I can think of...that's what I did. Might want to get the 86\87 to 84\85 crank sensor adapter too, the 86\87 style is an in-stock item at Advance, Autozone etc (at least it was). 84\85 must be ordered...and it's higher priced too.
